Description

Technical Field

[0001] The present invention relates to a probe capable of unbiased and comprehensive identification of target proteins of specific ligands directly from living cells or tissues reflecting phenotypes using chemical proteomics, and also relates to an identification method using the probe. Specifically, the present invention relates to a probe capable of detecting various target membrane proteins, including ion channels, GPCRs, or receptors forming multiple transmembrane segments or multimers, from living cells or brain slices as living tissue, and also relates to a method for identifying target membrane proteins using the probe. Background Art

[0002] In the field of chemical biology research, organic chemistry and molecular biology methods have been used to detect and quantify small amounts of biomolecules, such as proteins or physiologically active substances, as well as to understand the functions and reactions of these biomolecules. As part of these efforts, compounds that act specifically on biomolecules (i.e., chemical probes) are being developed with the goal of revealing the functions and reactions of biomolecules.

[0003] In this research field, chemical proteomics is one of the methods that uses organic chemistry methods to elucidate the structure and function of proteins.

[0004] Chemical proteomics is a method that allows for the unbiased and comprehensive identification of target proteins directly from living cells or tissues that reflect their phenotypes. It is believed to have a significant impact on drug development, for example, in the identification of unknown target proteins for drug candidates discovered in phenotypic screening or in the identification of antigens for antibodies with unknown antigens.

[0005] There are known conventional techniques for detecting known membrane proteins: a method for labeling living cells using a reactive group having photoaffinity (NPL 1), a method for identifying membrane proteins from the cell membrane fraction of living cells by proteomics (NPL 2), a method for detecting target membrane proteins from genetically engineered cells using chemical probes (NPLs 3 and 4), a method for detecting target membrane proteins from cultured cells or primary cultured cells using chemical probes (NPL 5), a method for detecting target proteins within cells or on the membrane from cultured cells using chemical probes (NPL 6), a method for performing fluorescent imaging of target membrane proteins on brain slices using chemical probes (NPL 7), and a method for identifying target membrane proteins using proteins such as growth factors (e.g., EGF and FGFR antibodies) (NPL 8).

[0006] Such target protein identification uses a probe with a part (ligand component) that specifically binds to the target protein. For example, a method for identifying a target protein using a compound that is bound to biotin at one end and to a ligand with affinity for the target protein at the other end is known (e.g., NPL 1 and 9). This probe is used to identify the target protein as follows: the target protein is bound to the probe via the ligand, a complex of biotin and avidin is then formed via biotin, and the target protein is isolated and purified using this complex as an indicator. However, membrane proteins with low expression levels are not easy to identify.

[0007] Specifically, NPL 1 discloses a method for detecting a target protein with affinity for a ligand using a probe containing a tetrazolium positioned near the ligand. This method involves irradiating the target protein with UV light after the ligand is bound to the target protein to form a covalent bond between the tetrazolium and the protein. Consequently, the protein bound to the ligand is not released during purification, for example.

[0008] NPL 9 discloses a probe having a cleavable moiety incorporated at a suitable position between a ligand and biotin to remove nonspecific proteins, including avidin, under mild conditions.

[0009] As a probe for identifying target glycoproteins present in living cells or biological fluids, PTL 1 discloses a trifunctional cross-linking reagent having: (i) a ligand-reactive group for coupling to a ligand of interest having at least one binding site on a target glycoprotein receptor, (ii) a hydrazone group for capturing oxidized receptor-glycoproteins, and (iii) an affinity group selected from azide and alkyne for detection, separation and purification of the captured glycoprotein.

[0010] However, none of the aforementioned methods are considered to be highly reproducible and practical techniques for identifying target membrane proteins from living cells or tissues that accurately reflect their phenotypes. This is because many proteins on the cell membrane are expressed at low levels, and the reactive groups widely used in known chemical proteomics techniques are inefficient at capturing target membrane proteins; this makes it difficult to specifically and sensitively detect the true target membrane proteins. Furthermore, nonspecific proteins generated by heat treatment of avidin beads or protein digestion on the beads are mixed in the purified sample. For these reasons, there are currently no reports of cases where target membrane proteins have been identified from living tissues using chemical proteomics.

The ligand can also be a protein, such as a protein receptor, or a cell surface protein, such as a domain of a cell surface protein receptor. In addition, the ligand can be a microorganism or a virus.

[0107] In the present invention, the ligand interacts with its target protein through a binding site. The binding site is a specific peptide fragment of the target protein, such as a specific amino acid sequence or a fragment of the three-dimensional structure of the target protein, and is referred to as a "binding site". For a ligand that binds to a binding site of a target protein (cell surface or secreted target protein), the term "interaction" includes temporary or permanent direct or indirect contact between the cell surface or secreted target protein and the ligand, and can be characterized by its binding affinity, i.e., the dissociation equilibrium constant, Kd. The typical binding affinity of a ligand for its target protein can be at least 10 -5 M, preferably 10 -6 M or higher, such as about 10 -7 M to about 10 -12 M.

[0108] As described above, the ligand can be any compound that has an affinity for the target protein; however, the ligand is preferably a compound that is used as an active ingredient in a pharmaceutical product for treating a disease in humans or non-human animals (a pharmaceutical compound). The pharmaceutical compound can be a small molecule compound, a medium molecular weight compound, a natural product, or a protein including an antibody. The pharmaceutical compound can be modified so as to bind to the ligand-binding component of the tetrafunctional compound according to the present invention, as long as the modification does not affect the affinity for the target protein. In the tetrafunctional chemical probe according to the present invention, the ligand can be bound to the reactive component via a spacer.

[0330] (II) Method for detecting target protein

[0331] The target protein in the sample can be detected using the tetrafunctional chemical probe according to the present invention. The target protein can be detected using the tetrafunctional chemical probe according to the present invention by a method comprising the following steps, although the method is not limited thereto.

[0332] (1) A step of reacting the tetrafunctional chemical probe with cells or tissues in a sample to allow the ligand of the tetrafunctional chemical probe to bind to the target protein.

[0333] (2) A step of forming a covalent bond between the reactive component (D) of the tetrafunctional chemical probe and the target protein.

[0334] (3) A step of purifying the fraction containing the target protein bound to the tetrafunctional chemical probe.

[0335] (4) A step of binding the biotin tag of the tetrafunctional chemical probe to avidin to form a conjugate of the tetrafunctional chemical probe and the avidin.

[0336] (5) A step of cleaving the formed conjugate of the tetrafunctional chemical probe and the avidin at the cleavable component of the tetrafunctional chemical probe.

[0337] (6) A step of detecting or identifying the target protein.

[0338] Each step is described below.

[0339] (1) Step of binding ligand to protein

[0340] Although not limited, this step can be performed as follows. Cells expressing the target protein are cultured at 37° C. in a 5% CO 2 atmosphere. After confirming that the cells have become confluent, the tetrafunctional chemical probe according to the present invention adjusted to a desired concentration with DMSO is added thereto, and the cells are allowed to stand at 37° C. in a 5% CO 2 atmosphere for approximately 30 to 60 minutes.

[0341] (2) Step of forming a covalent bond between the reactive component (D) of the tetrafunctional chemical probe and the target protein

[0342] Although not limited, this step can be performed by irradiating using a UV crosslinking agent at a wavelength of 254 to 365 nm, preferably 302 nm, for 1 second to 10 minutes, preferably 30 seconds to 5 minutes, more preferably 1 minute.

[0343] (3) Step of purifying the fraction containing the target protein bound to the tetrafunctional chemical probe

[0344] Although not limited to, this step can be performed, for example, by the following method. First, a tris homogenization buffer is added to the cells, and the mixture is homogenized and then centrifuged. The precipitate is separated and a sodium carbonate buffer is added thereto, followed by homogenization and incubation. The precipitate is separated by centrifugation to purify and collect a fraction (e.g., a membrane fraction) containing the target protein bound to the tetrafunctional chemical probe.

[0345] (4) combining the biotin tag of the tetrafunctional chemical probe with avidin to form a tetrafunctional chemical probe and Avidin conjugate steps

[0346] Although not limited to, this step can be performed as follows. For example, RIPA buffer containing 8M urea is added to the collected fractions, and the fractions are dissolved in the buffer using an ultrasonic disintegrator. The supernatant is separated by centrifugation and then streptavidin magnetic particles are added thereto. Thus, the biotin tag in the chemical probe binds to the avidin, thereby forming a conjugate of the tetrafunctional chemical probe and the avidin. In addition, the conjugate of the tetrafunctional chemical probe and the avidin can be purified and collected by performing magnetic separation according to a conventional method and discarding the supernatant.

[0347] (5) The tetrafunctional chemical probe is cleaved at the cleavable component of the tetrafunctional chemical probe to form a tetrafunctional chemical probe and an affinity Steps for the conjugate of Hesulin

[0348] Although not limiting, this step can be performed as follows: SDS (sodium dodecyl sulfate) and an aqueous hydrazine solution are added to the conjugate of the tetrafunctional chemical probe and avidin collected in the previous step (magnetic particle conjugate), and the mixture is allowed to stand at room temperature (1 to 30°C) for 30 minutes. This reaction allows the cleavable component in the tetrafunctional chemical probe to be cleaved, thereby separating the conjugate of the tetrafunctional chemical probe and avidin into a target protein binding domain and a biotin-avidin binding domain. The reaction solution is magnetically separated to obtain a supernatant; thereby, the target protein binding domain fragments can be collected.

[0349] (6) Steps for detecting or identifying target proteins

[0350] In detecting or identifying the target protein, the binding domain fragment of the target protein collected above can be optionally purified and hydrolyzed. Although not limited, specifically, for example, dithiothreitol is added to the supernatant obtained, and the mixture is stirred at 70°C for 15 minutes. Iodoacetamide is subsequently added thereto, and the mixture is allowed to stand at room temperature for 30 minutes. SP3 beads are added to the solution thus obtained, followed by MeCN, and then incubated for 18 minutes. Magnetic separation is performed after the incubation is complete to discard the supernatant. For peptide degradation, for example, a trypsin solution is added to the collected residue, and the mixture is incubated at 37°C for 12 to 16 hours. MeCN is added, and the mixture is incubated for 18 minutes, and then magnetic separation is performed to discard the supernatant. A TFA aqueous solution is added to the residue and the mixture is incubated for 3 minutes. Magnetic separation is performed to obtain a supernatant.

[0351] The peptides thus prepared were desalted and resuspended in a suitable buffer solution for analysis using a high-quality mass spectrometer. The mass spectrometer was operated in data-dependent acquisition mode, wherein the device automatically switches from MS to MS / MS mode for ion signals exceeding a predetermined threshold, in order to generate collision-induced dissociation (CID) or high-energy collision dissociation (HCD) spectra of the peptides. All MS / MS spectra were searched against a standard protein database.

[0352] The peptides thus obtained are analyzed. Any method available in the art for analyzing such compounds can be used, and a preferred method is mass spectrometry. Methods for performing mass spectrometry are well known to those skilled in the art (see, for example, Yates, J. Mass Spect. 33: 1-19 (1998); Kinter and Sherman, Protein Sequencing and Identification Using Tandem Mass Spectrometry, John Wiley and Sons, New York (2000); and Aebersold and Goodlett, Chem. Rev. 101: 269-295 (2001)). For high-resolution polypeptide fragment separation, liquid chromatography ESI-MS / MS or automatic LC-MS / MS using capillary reverse phase chromatography can be used as a separation method (Yates et al., Methods Mol. Biol. 112: 553-569 (1999)). Preferably, data-dependent collision-induced dissociation (CID) or high-energy collision dissociation (HCD) involving dynamic exclusion is used as the mass spectrometry of choice (Goodlett et al., Anal. Chem. 72: 1112-1118 (2000)). For such analysis, the mass spectrometer is typically operated in data-dependent acquisition mode, wherein the device automatically initiates switching from MS to MS / MS mode for ion signals exceeding a predetermined threshold to generate a collision-induced dissociation (CID) spectrum or a high-energy collision dissociation (HCD) spectrum of the peptide.

[0353] For protein identification, all MS / MS spectra were searched against standard protein databases using standard algorithms (eg, SEQUEST, Mascot, X!tandem, and MS Aanda) and typical filtering was performed to reduce false positive protein identifications to less than 1%.

[0354] In one embodiment, the membrane protein concentration in the sample can be quantitatively compared with the control sample. This allows the specific enrichment of the target membrane protein receptor to be detected. For this unlabeled mass spectrometry, the reversed-phase chromatography performed immediately before mass spectrometry can be displayed as an MS characteristic diagram, which plots the characteristics of retention time relative to mass / charge ratio. As detected by a mass spectrometer, the peptides in this diagram appear with a clear isotope pattern within a predetermined time and appear according to the ion current intensity determined by their amount in the sample. Once the peptide has been fragmented and identified by MS / MS analysis, this information can be assigned to the specific peptide features on the MS diagram and can be combined with the semi-quantitative data analysis using open source or commercial algorithms such as MaxQuant (Cox et al., Nature Biotechnology (2008) Vol. 26, pp. 1367-1372) or ProteomeDiscoverer (Thermo Fischer Scientific). The MS characteristic diagrams of different samples (e.g., sample and control) can be superimposed and compared to determine the ratio of the amount of the peptide. The ratio of the randomly labeled peptide derived from membrane proteins should be about 1. The membrane protein peptides that were specifically captured based on the ligand had a higher ratio than the control sample.

[0355] In another embodiment, alternative mass spectrometry-based quantification methods can be used, such as single reaction monitoring (SRM), stable isotope labeling with amino acids in cell culture (SILAC; e.g., Nilsson et al., Nat Methods (2010) Vol. 7(9), pp. 681-5), mass spectrometry data-independent acquisition (SWATH MS; see e.g., Gillet et al., Targeted Data Extraction of the MS / MS Spectra Generated by Data-independent Acquisition: A New Concept for Consistent and Accurate Proteome Analysis), and tandem mass tags (TMT; see e.g., Dayon et al., Relative Quantification of Proteins in Human Cerebrospinal Fluids by MS / MS using 6-Plex Isobaric Tags).

[0356] MS analysis can be replaced by other analytical methods. These other methods are included as part of the present invention.

[0357] The use of chemical probes according to the present invention allows the determination of the site of target protein binding to a ligand by identifying a peptide sequence to which a portion of the probe structure has been added using mass spectrometry. This enables identification of the binding site of the target protein to the ligand, thereby making identification of the target protein more accurate. Furthermore, this allows the design of probes with enhanced ability to detect target proteins.

[0807] Test example

[0808] The effects of the compounds of the present invention are described below by showing the test results using the tetrafunctional compounds of the present invention and representative compounds among the tetrafunctional chemical probes. However, the present invention is not limited to these test examples.

[0809] Experimental Example 1: Isolation and detection of target molecules from living cells using compound (CPP-127)

[0810] 1. Cell culture and methods of treating cultured cells with this compound

[0811] CHO-K1 cells stably expressing human dopamine receptor D2 (DRD2) were cultured on 10-cm culture plates until they became confluent.

[0812] The cells were washed with culture medium, and the culture medium was replaced with a culture medium containing DMSO or an unmodified ligand, and then reacted for 30 minutes. Subsequently, the culture medium was discarded and replaced with a culture medium containing the compound (CPP-127) synthesized in Production Example 12, and the cells were allowed to stand at 37°C for 30 minutes. The culture medium was discarded, and the cells were washed with PBS. PBS (1 ml) was added to the cells on the culture plate, and the cells were then irradiated with 302 nm UV light using a UV crosslinker for 1 minute. Cells were collected using a cell scraper after UV irradiation, and the collected cell mass was cryopreserved at -80°C.

[0813] 2. Preparation and Purification of Membrane Fraction Proteins

[0814] The cryopreserved cells were suspended in 50 mM Tris homogenization buffer (pH 7.4, 2.5 mM EDTA, 5 mM MgCl 2 , 320 mM sucrose) and homogenized using an ultrasonic instrument. The homogenized suspension was centrifuged using a centrifuge (1,000 g, 15 minutes, 4° C.). The supernatant obtained after centrifugation was transferred to another tube and centrifuged (30,000 × g, 30 minutes, 4° C.). After centrifugation, the supernatant was discarded, and 100 mM sodium carbonate buffer (Na 2 CO 3 ) was added to the precipitate, which was then homogenized using an ultrasonic instrument and incubated on ice for 10 minutes. The suspension was centrifuged by ultracentrifugation (45, 2000 × g, 30 minutes, 4° C.), the supernatant was discarded, and the resulting precipitate was rinsed with Milli-Q water and used as a membrane fraction protein.

[0815] 3. Membrane Protein Elution

[0816] Membrane lysis buffer (50mM Tris-HCl (pH 7.5), 150mM NaCl, 0.1% SDS, 0.5% SDC, 1% Triton-X-100, 8M urea) was added to the membrane fraction protein prepared by the above method, and the membrane fraction protein was dissolved using a sonicator. Streptavidin beads (#88816, Thermo Fisher Scientific) were added to the dissolved membrane protein solution, and the biotin-labeled protein was adsorbed onto the beads by stirring and mixing for 60 minutes. After the beads were washed with membrane lysis buffer, 40 μL of 2% N2H4 solution containing 0.05% SDS was added, and the beads were allowed to stand at room temperature for 30 minutes. The beads were removed by magnetic separation and the solution was collected. The collected solution was neutralized by adding 20% TFA solution and then concentrated using a centrifugal evaporator. Dithiothreitol and iodoacetamide were added to the concentrated solution for reduction and alkylation, and trypsin solution was added, and then digested at 37°C overnight.

[0817] 4. LC-MS Analysis and Identification of Target Proteins

[0818] The obtained tryptic digest was desalted and purified, and protein analysis was performed by LC-MS. LC-MS was performed using a combined LC-MS system utilizing a nano-HPLC device (Ultimate 3000, Thermo Scientific) and a mass spectrometer (Q Exactive, Thermo Scientific). In the nano-HPLC device, a column (stationary phase) consisting of a capture column (C18Acclaim PepMap, Thermo Scientific) and a chip column (75 μm i.d., 12 cm long, 3 μm C18 particles, NikkyoTechnos, Co., Ltd.) was used, and a 0.1% formic acid-acetonitrile system was used as the mobile phase for gradient analysis by reversed-phase chromatography. The flow rate was 300 nl / min, and the peptides were eluted with a linear gradient of acetonitrile concentration from 4% to 35% over a period of 48 minutes. Mass spectrometry was performed in positive ion mode by nano-electrospray ionization. Full scan MS spectra are obtained in the m / z range of 380 to 1600, and product ion spectra are measured in data dependent acquisition mode. The data obtained by LC-MS are analyzed by Proteome Discoverer 2.2 analysis software (PD 2.2, Thermo Fisher Scientific). For protein identification, the search engine Sequest provided in PD 2.2 is used to search in the database downloaded from UniProt. False discovery rate is used to calculate. After filtering to make the false positive protein identification rate less than 1%, the protein with a PSM value greater than or equal to 5 is considered as the protein identified, so as to select more reliable candidate proteins. In addition, the number of unique peptides identified is used to narrow the data range. In quantitative analysis, protein is quantitatively analyzed by the quantitative method LFQ provided in PD 2.2, and quantitative comparative analysis is carried out with the unmodified ligand treatment group to distinguish the proteins collected specifically. Analysis is carried out in two independent experiments, and the result can be expressed as the ratio relative to the unmodified ligand treatment group.

[0819] 5. Results

[0820] Figure 1 The results are shown. Figure 1 As shown in the results, when the tetrafunctional chemical probe of the present invention (compound (CPP-127)) was used, the detection of dopamine receptor D2 was significantly inhibited in the unmodified ligand-treated group, confirming that dopamine receptor D2 (DRD2) was specifically collected. Experimental Example 2: Isolation and Detection of Target Molecules from Living Tissue Using Compounds (CPF-224, CPF-202, and CPF-242)

[0821] By isoflurane inhalation, DBA / 2CrSlc mice are anesthetized, then decapitated and brain is taken out rapidly.The brain taken out is soaked 60 seconds at 0 ℃ in artificial cerebrospinal fluid (ACSF), while constantly blasting gas mixture (95% O , 5% CO ). Remove olfactory bulb and cerebellum with a scalpel, and use viscose glue to fix brain to the sample carrier of a vibrating blade microtome (Leica, VT1200). At 0 ℃, constantly blast into the ACSF of described mixed gas and prepare the brain slice (thickness is the thin slice of 0.3mm) containing striatum and hippocampus. Section is placed in the culture dish containing artificial cerebrospinal fluid. Add unmodified part or DMSO, and culture dish was placed 5 minutes in room temperature. Subsequently add the compound (CPF-224) produced in Production Example 10 or the compound (CPF-202) produced in Production Example 8, and culture dish was placed 30 minutes in room temperature. The solution was removed and the sections were irradiated with UV light (in the case of CPF-224 and CPF-202, irradiated with 302nm UV light for 1 minute, and in the case of CPF242, irradiated with 365nm UV light for 15 minutes). The sections were washed with PBS and collected, and the supernatant was removed by centrifugation (3000 × g, 4°C, 5 minutes). The resulting sediment was analyzed by the same method as in Experimental Example 1. The analysis was performed in two independent experiments, and the results can be expressed as a ratio relative to the unmodified ligand-treated group.

[0822] Figure 2 Results obtained using compound (CPF-224) are shown. Figure 3 Results obtained using compound (CPF-202) are shown. Figure 4 The results obtained using the compound (CPF-242) are shown. As shown in these figures, when the tetrafunctional chemical probes of the present invention, CPF-224, CPF-202, and CPF242, were used, the detection of AMPA-type glutamate receptors (Gria1, Gria2, Gria3, Gria4) and GABA receptor subunits (Gabra1, Gabra2, Gabra5, Gabrg2) in brain tissue was significantly inhibited in the unmodified ligand-treated group, confirming that the membrane proteins were specifically collected.

[0823] Experimental Example 3: Capturing cell surface antigens using labeled antibodies

[0824] Antigen molecules were obtained from THP-1 cells using an anti-CD71 antibody labeled with CPA-321 produced in Production Example 21 or an anti-mouse IgG1 control antibody labeled with CPA-321 produced in Production Example 21. Specifically, THP-1 cells were collected and washed with SB buffer (PBS buffer containing 2% FCS). The washed cells were suspended in SB buffer containing 0.1% Fc blocking reagent (Invitrogen, 16-9161-73) and reacted at 4°C for 15 minutes. The supernatant was removed by centrifugation (600 × g, 3 minutes, 4°C), and an antibody solution was added (obtained by adding SB buffer to a solution (20 μg) of the antibody labeled with CPA-321 produced in Production Example 21 so that the total volume was 1 ml), and then reacted at 4°C for 20 minutes. The antibody solution was removed by centrifugation, the cells were washed with SB buffer, and then suspended in 0.5 ml SB buffer. The cell suspension was irradiated with a 302nm UV tube for 1 minute, and the SB buffer was removed by centrifugation. The obtained cells were analyzed by the method described in Experimental Example 1. The analysis was performed in two independent experiments, and the results were expressed as the ratio of the amount of protein obtained using the anti-CD71 antibody to the amount of protein obtained in the case of a mouse IgG1 isotype control antibody (anti-mouse IgG antibody) ( Figure 5 ).

[0825] like Figure 5 As shown in , two analytical tests confirmed the significant acquisition of TFRC (CD71). Experimental Examples 4 to 13: Capturing Cell Surface Antigens Using Labeled Antibodies (1)

[0826] The investigation of the antigen molecules from the cells shown in Table 2 was carried out using the labeled antibodies shown in Table 2. Specifically, the cells shown in Table 2 were washed with SB buffer (PBS buffer containing 2% FCS), suspended in SB buffer containing 0.1% Fc blocking reagent (Invitrogen, 16-9161-73), and reacted at 4°C for 15 minutes. Each supernatant was removed individually by centrifugation (600×g, 3 minutes, 4°C), and each solution containing the labeled antibody produced according to the labeled antibody production method described below was added individually, and then reacted at 4°C for 20 minutes. Each antibody solution was removed individually by centrifugation, and the cells were washed with SB buffer and then suspended in 0.5ml SB buffer. Each cell suspension was irradiated individually with ultraviolet light of the wavelength shown in the table for the time period shown in the table, and the SB buffer was removed by centrifugation. The collected cells were analyzed by the method shown in Experimental Example 1. The analysis was carried out in two independent experiments, and the detection amounts of the membrane proteins to be analyzed shown in the table were compared ( Figures 6 to 8 ).

[0827] Production of labeled antibodies (Test Examples 4 to 12)

[0828] The antibodies shown in Table 2 are placed separately in independent tubes and diluted to a final concentration of about 0.05 mg / ml with NHS labeling buffer (25 mM HEPES-NaOH pH 8.2, 150 mM NaCl). A solution of the probe shown in each of Table 2 of about 0.9 μL in DMSO (10 mg / ml in DMSO) is added thereto separately, followed by reaction at room temperature for 2 hours. Subsequently, about 5 μL lysine solution (100 mM) is added thereto, followed by reaction at room temperature for 20 minutes. The resulting solution is stored at 4°C until use.

[0829] Production of labeled ligand (Test Example 13)

[0830] 12.5 μg of His-tagged EGF was placed in a tube and diluted with NHS labeling buffer to a final concentration of approximately 0.25 mg / ml. To 48 μL of this solution, 2 μL of 5 mM CPA-354 was added to prepare a labeled ligand solution. This solution was stored at 4°C until use.

[0831] Table 2

[0832]

[0833] Experimental Example 14: Capturing cell surface antigens using labeled antibodies (2)

[0834] The investigation of antigen molecules from A431 cells was carried out using labeled OKT9 produced by the method shown in Table 3. First, the cells were washed with SB buffer (PBS buffer containing 2% FCS). SB buffer containing 0.1% Fc blocking reagent (Invitrogen, 16-9161-73) was then added, and the cells were reacted at 4°C for 15 minutes. The supernatant was removed, and 250 μL of ligand solution diluted 10 times with SB buffer was added, and then reacted at 4°C for 20 minutes. The ligand solution was removed, the cells were washed with PBS, and then irradiated with 302nm UV light for 1.5 minutes. Proteins were extracted from the cells using a lysis buffer containing 1% NP-40 and analyzed by the method shown in Experimental Example 1. The amount of CD71 detected when using each ligand formed in the probe was compared with the amount detected when using the OKT9 antibody not formed in the probe as a negative control (no probe) ( Figure 9 ).

[0835] Production of labeled antibodies

[0836] (1) 10 μg of anti-CD71 antibody OKT9 (Thermo Fisher Scientific, catalog number 16-0719-85) was placed in a tube and diluted with NHS labeling buffer (25 mM HEPES-NaOH pH 8.2, 150 mM NaCl) to a final concentration of about 0.1 mg / ml. 0.9 μL of CPA-321 solution (10 mg / ml in DMSO) was added thereto, followed by reaction at room temperature for 2 hours. Subsequently, about 5 μL of lysine solution (100 mM) was added thereto, followed by reaction at room temperature for 20 minutes. The resulting solution was stored at 4°C until use.

[0837] (2) 10 μg of anti-CD71 antibody OKT9 was placed in a tube and 5 μL of 30 mM sodium periodate (in phosphate buffer, pH 6.5) was added. Phosphate buffer (pH 6.5) was then added to bring the total volume to 100 μL. After reacting at room temperature for 15 minutes, the solvent was replaced with PBS using a Zeba Spin column (Thermo Scientific). 1 μL of a 500 mM 5-MA aqueous solution was added to 100 μL of the resulting antibody solution. 1 μL of a 10 mg / ml CPA-342 or CPA-344 solution in DMSO was subsequently added and the mixture was reacted at room temperature for 1.5 hours in the dark. After the reaction, the solvent was replaced with PBS using a Zeba Spin column and excess reagents were removed.

[0840] Experimental Example 17: Capturing cell surface antigens using labeled antibodies (secondary antibody method)

[0841] The investigation of antigen molecules from THP-1 cells is carried out using the labeled second antibody produced by the production method of the second antibody for CBP-198 labeling. Specifically, THP-1 cells are washed with SB buffer (PBS buffer containing 2% FCS) and suspended in SB buffer containing 0.1% Fc blocking reagent (Invitrogen, 16-9161-73), and the cells are reacted at 4 ° C for 15 minutes. The supernatant is removed by centrifugation (600 × g, 3 minutes, 4 ° C). An anti-CD71 antibody DF1513 solution diluted to 5 μg / mL with SB buffer is added to the cells, and the cells are reacted at 4 ° C for 20 minutes. The antibody solution is removed by centrifugation, and the cells are washed with SB buffer. Subsequently, the cells are suspended in a solution (obtained by adding SB buffer to a total volume of 1 ml to the labeled second antibody produced by the production method for the second antibody for CPA-503 labeling) and reacted at 4 ° C for 20 minutes. The antibody solution is removed by centrifugation, and the cells are washed with SB buffer and then suspended in 0.5 ml SB buffer. The cells were irradiated with 365 nm UV light for 15 minutes, and the SB buffer was removed by centrifugation. The collected cells were analyzed by the method described in Experimental Example 1. The analysis was performed in two independent experiments, and the amount of CD71 detected was compared.

[0842] As a comparative example, the amount of CD71 detected was calculated in the same manner as in Test Example 11, except that the anti-CD71 antibody DF1513 was used instead of the anti-CD71 antibody OKT9 ( Figure 10 ).

[0843] Production of CPA-503 labeled secondary antibodies

[0844] Goat anti-mouse IgG antibody (5 μg) was placed in a tube and diluted with NHS labeling buffer (25 mM HEPES-NaOH pH 8.2, 150 mM NaCl) to a final concentration of approximately 0.05 mg / ml. About 0.9 μL of a DMSO solution of CPA-503 (10 mg / ml in DMSO) was added, followed by reaction at room temperature for 2 hours. Subsequently, about 5 μL of a lysine solution (100 mM) was added, followed by reaction at room temperature for 20 minutes. The resulting solution was stored at 4°C until use.

[0845] By using the secondary antibody method, membrane proteins that could not be detected by the primary antibody method can be detected.
