[0014] While various embodiments of the present invention have been shown and described herein, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It is understood that various alternatives to the embodiments of the invention described herein may be employed.
[0015] Whenever the terms "at least," "greater than," or "greater than or equal to" precede the first number in a series of two or more numbers, the terms "at least," "greater than," or "greater than or equal to" apply to each number in the series. For example, 1, 2, or 3 or more is equivalent to 1 or more, 2 or more, or 3 or more.
[0016] Whenever the terms "no more than," "less than," or "less than or equal to" precede the first number in a series of two or more numbers, the terms "no more than," "less than," or "less than or equal to" apply to each of the numbers in the series. For example, 3, 2, or 1 or less is equivalent to 3 or less, 2 or less, or 1 or less.
[0017] Certain inventive embodiments herein contemplate numerical ranges. When a range exists, the range includes the endpoints of the range. Furthermore, any subranges and values within the range exist as if explicitly written out. The term "about" or "approximately" may mean within an acceptable error range for a particular value, which depends in part on how the value is measured or determined, for example, on the limitations of the measurement system. For example, "about" may mean within 1 or more than 1 standard deviation, as is customary in the art. Alternatively, "about" may mean within a range of up to 20%, up to 10%, up to 5%, or up to 1% of a given value. When a particular value is described in this application and claims, unless otherwise specified, the term "about" may be assumed to mean within an acceptable error range for the particular value.
[0018] definition As used herein, the terms "individual," "patient," or "subject" refer to an individual who has been diagnosed with, is suspected of having, or is at risk of developing at least one disease for which the compositions and methods described are useful for treating. In certain embodiments, the individual is a mammal. In certain embodiments, the mammal is a mouse, rat, rabbit, dog, cat, horse, cow, sheep, pig, goat, llama, alpaca, or yak. In certain embodiments, the individual is a human.
[0019] The terms "polypeptide" and "protein" are used interchangeably to refer to a polymer of amino acid residues and are not limited to a minimum length. Polypeptides, including the provided polypeptides, antibody chains, and other peptides, such as linkers and connecting peptides, may contain amino acid residues, including natural and / or non-natural amino acid residues. The term also includes post-expression modifications of the polypeptide, such as glycosylation, sialylation, acetylation, phosphorylation, and the like. In some aspects, the polypeptide may contain modifications to the native or naturally occurring sequence, so long as the protein maintains the desired activity. These modifications may be deliberate, such as through site-directed mutagenesis, or may be accidental, such as due to mutations of the host that produces the protein, or errors due to PCR amplification.
[0020] Percent sequence identity (%) to a reference polypeptide sequence is the percentage of amino acid residues in a candidate sequence that are identical to the amino acid residues in the reference polypeptide sequence, after aligning sequences and introducing gaps as necessary to achieve maximum sequence identity percentage, without considering any conservative substitutions as part of sequence identity. Alignment for the purpose of determining percent amino acid sequence identity can be achieved in various known ways, for example, using publicly available computer software such as BLAST, BLAST-2, ALIGN, or Megalign (DNASTAR) software. Suitable parameters for aligning sequences can be determined, including the algorithm required to achieve maximum alignment over the entire length of the sequences being compared. However, for the purposes herein, percent amino acid sequence identity values are generated using the sequence comparison computer program ALIGN-2. The ALIGN-2 sequence comparison computer program was created by Genentech, Inc., and the source code has been submitted with user documentation to the United States Copyright Office, Washington, DC, 20559, and is registered under United States Copyright Registration No. TXU510087. The ALIGN-2 program is publicly available from Genentech, Inc., South San Francisco, Calif., or may be compiled from the source code. The ALIGN-2 program must be compiled for use on UNIX operating systems, including Digital UNIX V4.0D. All sequence comparison parameters are set by the ALIGN-2 program and do not vary.
[0021] In the situation where ALIGN-2 is used for amino acid sequence comparison, the % amino acid sequence identity of a given amino acid sequence A to a given amino acid sequence B (which may alternatively be referred to as a given amino acid sequence A having or containing a particular % amino acid sequence identity to a given amino acid sequence B) is calculated as 100 x the fraction X / Y, where X is the number of amino acid residues scored as identical matches by the sequence alignment program ALIGN-2 in the alignment of A and B programs, and Y is the total number of amino acid residues in B. It will be understood that if the length of amino acid sequence A is not equivalent to the length of amino acid sequence B, the % amino acid sequence identity of A to B is not equivalent to the % amino acid sequence identity of B to A. Unless otherwise specified, all amino acid sequence identity % values used herein are obtained using the ALIGN-2 computer program as described in the immediately preceding paragraph.
[0022] In some embodiments, amino acid sequence variants of the polypeptides provided herein are contemplated. Variants typically differ from the polypeptides specifically disclosed herein in one or more substitutions, deletions, additions, and / or insertions. Such variants may occur naturally or may be synthetically generated, for example, by modifying one or more of the above polypeptide sequences of the present invention, evaluating the biological activity of one or more of the polypeptides described herein, and / or using any of a number of known techniques. For example, it may be desirable to improve the binding affinity and / or other biological properties of the antibody. Amino acid sequence variants of antibodies may be prepared by introducing appropriate modifications into the nucleotide sequence encoding the antibody or by peptide synthesis. Such modifications include, for example, deletions and / or insertions and / or substitutions of residues within the amino acid sequence of the antibody. Any combination of deletions, insertions, and substitutions may be made to arrive at the final construct, provided that the final construct has the desired characteristics, for example, antigen binding.
[0023] In some embodiments, "antigen-binding domain" or "antigen-interacting domain" refers to an immunoglobulin derivative having antigen-binding properties, i.e., an immunoglobulin polypeptide or fragment thereof that contains an antigen-binding site. Optionally, the binding domain comprises a variable domain of an antibody or fragment thereof. Each antigen-binding domain is formed by an antibody, i.e., an immunoglobulin, in which the variable heavy chain domain (VH) and the antibody variable light chain domain (VL) bind to the same epitope, but the variable heavy chain domain (VH) comprises three heavy chain complementarity determining regions (CDRs), CDR1, CDR2, and CDR3, and the variable light chain domain (VL) comprises three light chain complementarity determining regions (CDRs), CDR1, CDR2, and CDR3. In some examples, the binding domain according to some embodiments herein lacks an immunoglobulin constant domain. In some examples, the variable light chain and heavy chain domains that form the antigen-binding site are covalently linked to each other, e.g., by a peptide linker, or in other examples, the variable light chain and heavy chain domains are non-covalently associated with each other to form the antigen-binding site. Binding domains and interaction domains also refer to antibody fragments or antibody derivatives, including, for example, Fab, Fab', F(ab')2, Fv fragments, single chain Fv, tandem single chain Fv ((scFv)2), Bispecific T-cell Engagers (BiTEs®), Dual Affinity Retargeting Antibodies (DART™), diabodies, DuoBody® IgG molecules, single domain antibodies (e.g., VHH), TriTac, etc. In further particular examples, the binding domain is multivalent, i.e., has two, three, or more binding sites for one or more antigens.
[0024] In certain embodiments, the antigen-binding or antigen-interacting domain comprises a sequence derived from the complementarity determining region of an antibody. The terms "complementarity determining region" and "CDR", which are synonymous with "hypervariable region" or "HVR", are known in the art to refer to non-contiguous sequences of amino acids in an antibody variable region that confer antigen specificity and / or binding affinity. Generally, each heavy chain variable region has three CDRs (CDR-H1, CDR-H2, CDR-H3), and each light chain variable region has three CDRs (CDR-L1, CDR-L2, CDR-L3). "Framework region" and "FR" are known in the art to refer to the non-CDR portions of the heavy and light chain variable regions. Generally, each full-length heavy chain variable region has four FRs (FR-H1, FR-H2, FR-H3, and FR-H4), and each full-length light chain variable region has four FRs (FR-L1, FR-L2, FR-L3, and FR-L4).The exact amino acid sequence boundaries of a given CDR or FR can be determined by Kabat et al. (1991), "Sequences of Proteins of Immunological Interest," 5th ed., Public Health Service, National Institutes of Health, Bethesda, MD ("Kabat" numbering), Al-Lazikani et al. (1997), JMB 273, 927-948 ("Chothia" numbering scheme), MacCallum et al., "Antibody-antigen interactions: Contact analysis and binding site topography," J. Mol. Biol. 262, 732-745 (1996), ("Contact" numbering scheme), Lefranc MP et al., "IMGT unique numbering for immunoglobulin and T cell receptor variable domains and Ig superfamily V-like domains," Dev Comp Immunol, 2003 Jan;27(1):55-77 (the "IMGT" numbering scheme), Honegger A and Pluckthun A, "Yet another numbering scheme for immunoglobulin variable domains: an automatic modeling and analysis tool", J Mol Biol, 2001 Jun 8;309(3):657-70 (the "Aho" numbering scheme), and Whitelegg NR and Rees AR, "WAM: an improved algorithm for modelling antibodies on the WEB", Protein Eng. 2000 Dec;13(12):819-24 (the "AbM" numbering scheme).In certain embodiments, the CDRs of the antibodies described herein can be defined by a method selected from Kabat, Chothia, IMGT, Aho, AbM, or a combination thereof.
[0025] The boundaries of a given CDR or FR may vary depending on the scheme used for identification. For example, the Kabat scheme is based on structural alignment, while the Chothia scheme is based on structural information. The numbering in both the Kabat and Chothia schemes is based on the most common antibody region sequence lengths, with insertions provided by the insertion letter, e.g., "30a", and deletions occurring in some antibodies. The two schemes place certain insertions and deletions ("indels") in different positions, resulting in differential numbering. The Contact scheme is based on the analysis of complex crystal structures and is similar in many ways to the Chothia numbering scheme.
[0026] In certain embodiments, the antigen-binding domain or antigen-interacting domain comprises a sequence derived from the complementarity determining region of an antibody. The term "variable region" or "variable domain" refers to the domain of an antibody heavy or light chain that is involved in binding the antibody to an antigen. The variable domains of the heavy and light chains of natural antibodies (VH and VL, respectively) exhibit a similar overall structure, and each domain contains four conserved framework regions (FR) and three CDRs (see, for example, Kindt et al., Kuby Immunology, 6th Edition, WH Freeman and Co., p. 91 (2007)). A single VH or VL domain may be sufficient to confer antigen-binding specificity. Moreover, antibodies that bind to a specific antigen can be isolated using the VH or VL domain from an antibody that binds the antigen to screen libraries of complementary VL or VH domains, respectively (see, e.g., Portolano et al., J. Immunol. 150:880-887 (1993); Clarkson et al., Nature 352:624-628 (1991)).
[0027] In certain embodiments, the antigen-binding or antigen-interacting domain is "humanized". A "humanized" polypeptide or antibody is one in which all or nearly all CDR amino acid residues are derived from non-human CDRs and all or nearly all FR amino acid residues are derived from human FRs. A humanized antibody may optionally contain at least a portion of an antibody constant region derived from a human antibody. A "humanized form" of a non-human antibody typically refers to a variant of a non-human antibody that has undergone humanization to reduce immunogenicity to humans while retaining the specificity and affinity of the parent non-human antibody. In some embodiments, some FR residues in a humanized antibody are replaced with the corresponding residues derived from a non-human antibody (e.g., the antibody from which the CDR residues are derived), e.g., to restore or improve antibody specificity or affinity.
[0028] Among the polypeptides and antibodies provided are human antibodies. A "human antibody" is an antibody having an amino acid sequence that corresponds to that of an antibody produced by a human or human cell, or a non-human source, utilizing a human antibody repertoire, including a human antibody library, or other human antibody-encoding sequences. The term excludes humanized forms of non-human antibodies that include a non-human antigen-binding region, such as those in which all or nearly all CDRs are non-human. Although the methods and systems of the present disclosure are described herein as antibody-based therapeutics, in some embodiments, they are used to image the interaction of non-therapeutic antibodies or antibody derivatives (e.g., portions of antibodies) with cells.

[0030] The polypeptides described herein may be encoded by nucleic acids. A nucleic acid is a type of polynucleotide that contains two or more nucleotide bases. In certain embodiments, a nucleic acid is a component of a vector that can be used to introduce a polynucleotide encoding a polypeptide into a cell. As used herein, the term "vector" refers to a nucleic acid molecule that can transport another nucleic acid to which it is linked. One type of vector is a genomic integration vector or "integration vector" that can be integrated into the chromosomal DNA of a host cell. Another type of vector is an "episomal" vector, e.g., a nucleic acid capable of extrachromosomal replication. A vector capable of inducing the expression of a gene to which it is operably linked is referred to herein as an "expression vector." Suitable vectors include plasmids, bacterial artificial chromosomes, yeast artificial chromosomes, viral vectors, and the like. In an expression vector, regulatory elements such as promoters, enhancers, polyadenylation signals, and the like, for use in controlling transcription can be derived from mammalian, microbial, viral, or insect genes. The ability to replicate in a host, usually conferred by an origin of replication, and a selection gene to facilitate recognition of transformants may further be incorporated. Vectors derived from viruses such as lentiviruses, retroviruses, adenoviruses, adeno-associated viruses, etc. may be employed. Plasmid vectors can be linearized for integration into chromosomal locations. Vectors can include sequences that direct site-specific integration (e.g., AttP-AttB recombination) into a defined location or a restricted set of sites in the genome. Additionally, vectors can include sequences derived from transposable elements.
[0031] As used herein, the terms "homologous", "homology", or "percent homology", when used herein to describe an amino acid sequence or a nucleic acid sequence relative to a reference sequence, can be determined using the formula described by Karlin and Altschul (Proc. Natl. Acad. Sci. USA 87:2264-2268, 1990, revised Proc. Natl. Acad. Sci. USA 90:5873-5877). Such formula is incorporated into the Basic Local Alignment Search Tool (BLAST) program of Altschul et al. (J. Mol. Biol. 215:403-410, 1990). Percent sequence homology can be determined using the most recent version of BLAST as of the filing date of this application.
[0032] Nucleic acids encoding the polypeptides described herein can be used to infect, transfect, transform, or otherwise transfect suitable cells with the nucleic acid, thus allowing production of the polypeptide for commercial or therapeutic use. Standard cell lines and methods for producing antibodies or polypeptides from large scale cell culture are known in the art. See, for example, Li et al., "Cell culture processes for monoclonal antibody production," Mabs. 2010 Sep-Oct;2(5):466-477. In certain embodiments, the cell is a eukaryotic cell. In certain embodiments, the eukaryotic cell is a mammalian cell. In certain embodiments, the mammalian cell is a cell line useful for producing a polypeptide or antibody and is a Chinese Hamster Ovary (CHO) cell, an NS0 mouse myeloma cell, or a PER.C6® cell. In certain embodiments, the nucleic acid encoding the antibody is integrated into a genomic locus of a cell useful for producing a polypeptide or antibody. In certain embodiments, described herein are methods of making an antibody comprising culturing cells containing nucleic acid encoding the antibody under in vitro conditions sufficient to allow production and secretion of the antibody.
[0033] Although the methods and systems described herein are described in some embodiments for use in disease state differentiation, treatment design, and therapeutic target identification, the methods and systems described herein can be used for a variety of applications. For example, the databases, methods, and systems described herein can be used for patient selection (e.g., cancer type or study group selection). In another example, the databases, methods, and systems described herein can be used for combination therapy selection (e.g., drug combination selection). In another example, the databases, methods, and systems described herein can be used for drug discovery (e.g., discovery of novel targets or therapeutic compounds). In some embodiments, the multiple extracellular receptors described herein are multiple of the same extracellular receptor. In some embodiments, the multiple extracellular receptors described herein are multiple of different extracellular receptors. In another example, the databases, methods, and systems described herein can be used in determining therapeutics that can be repurposed for different applications (e.g., determining survival rates for therapeutics approved for use in applications different from those for which the therapeutics were approved).
[0034] Although the database, method, and system of the present disclosure are described herein with respect to antibody fragments or derivatives, they can be used to test the effect of complete antibodies on a sample. For example, an antibody can be contacted with a sample, and the cellular characteristics of the sample can be recorded in the database. Examples of antibodies include, but are not limited to, IgA, IgD, IgE, IgG, IgM, IgT / Z, IgY, IgW, and the like. In some embodiments, the antibody is an antibody associated with a CAR T cell. In some embodiments, the antibody is an antibody-drug conjugate. In some embodiments, a ribonucleic acid (RNA) aptamer is used in place of the antibody. In some embodiments, a natural receptor or ligand is used in place of the antibody.
[0035] As used herein, molecular signature or molecular fingerprint is defined as all or part of the composition or state of one extracellular molecule on the cell surface that is composed of at least one cell characteristic.As used herein, cell signature or cell fingerprint is defined as all or part of the composition or state of two or more extracellular molecules on the cell surface that is composed of at least one cell characteristic.As used herein, tissue signature or tissue fingerprint is defined as the molecular signature or fingerprint or cell signature or fingerprint on the surface of two or more cells (or cell aggregates) in a tissue or sample.
[0036] Method for generating a database containing cell characteristics Cancer cells are morphologically and functionally different from normal cells, and different cell signaling pathways operate. Extracellular receptors may cluster (or appear differently) in lipid rafts during cell signaling, amplifying signals inside the cell. The specific characteristics of extracellular receptors may differ between cancer cells and normal cells. In one aspect of the present disclosure, super-resolution microscopy (SRM) at a large scale and pharmacologic relevant binders to known cancer antigens are used to build a high-content normal / cancer cell (tissue) database. This may be directly translatable to therapeutic strategies and may be used throughout testing and development. The database may be used for target selection and validation (as well as new target discovery) for monospecific, bispecific, and multispecific therapy, drug design and validation, combination therapy selection for clinical trials, cancer indication selection for clinical trials, and patient selection for clinical trials. Features are characterized as to whether the feature is present, and if so, its location, nearest neighbors, whether internalized, etc. are determined.
[0037] In some embodiments, the present disclosure provides a database of cellular interactions that can be used in a variety of different applications. In some embodiments, the database provides new information about the interactions of therapeutics (e.g., antibody-based therapeutics, small molecule therapeutics, etc.) with both diseased and healthy cells. In some embodiments, the information can then be used to improve the efficacy of the screened therapeutics by better targeting different types of cells. In some embodiments, the information in the database can be used to characterize properties in diseased and non-disease cells, and subsequently interpret patterns that provide information about diseased and non-disease cells. In some embodiments, the information in the database is used for target selection, drug design, lead and development candidate selection, patient selection for clinical trials, and / or indication selection.
[0038] In another aspect of the disclosure, the spatially localized affinity (K) of T cell engagers (TCEs) or other binding molecules (e.g., antibody-based therapeutics) to the cell surface is measured. d ) are derived from single molecule tracking (SMT) experiments and matched to the cellular properties of cells in the database to provide two-dimensional (2D) K d The SMT produces a profile (see Figure 2). The SMT is the on-rate (k on ) and off-rate (k off ) which allows for the measurement of the spatially localized affinity (K) of a binding molecule or TCE on the surface of a cell (e.g., a cancer cell or other cell). d =k off / k on When a binding molecule or TCE contains a repeating single variable domain (VHH) on the heavy chain and / or two or more different VHHs that bind to different targets on the cell surface, there is an avidity effect when those targets cluster to form multimers. Thus, whenever a target clusters to form a structure that is recognized by the binding molecule / TCE, it will have a higher affinity (lower K d ) exists. dUsing the pattern and matching it to the cell surface targeting pattern (cell characteristics) of the cells observed in the SRM images, the binding behavior of the binding molecule / TCE to the surface of a separate cell or tissue can be predicted by recording SRM images of the separate cell / tissue in the presence of the binding molecule / TCE, assuming that the target presentation / cell characteristics are approximately the same in both cells / tissues. This strategy can be beneficial, for example, to predict the binding behavior of the binding molecule / TCE to normal or cancerous cells or tissues.

[0054] Super-resolution microscope In some embodiments, the super-resolution microscope comprises a deterministic super-resolution microscope. In some embodiments, the deterministic super-resolution microscopy uses light structuring to determine spatial information below the diffraction limit of a sample. For example, the deterministic super-resolution microscope can use a depletion ring to refine the excitation spot of the microscope. In some embodiments, the super-resolution microscope is a stimulated emission depletion (STED) microscope, a ground state depletion (GSD) microscope, a saturated structured illumination microscopy (SSIM), a super-resolution orthogonal deterministic imaging (SODI), or the like. In some embodiments, the super-resolution microscope is a MINFLUX microscope. For example, the super-resolution technology can be the MINFLUX technology developed by Abberior Instruments. MINFLUX is a super-resolution fluorescence microscopy that can provide resolution in the 1-3 nanometer (nm) range by localizing individual switchable fluorophores with a probing donut-shaped excitation beam (see, e.g., Gwosch et al., "MINFLUX nanoscopy delivers 3D multicolor nanometer resolution in cells," Nature Methods, vol. 17, pp. 217-220, February 2020). In some embodiments, the super-resolution microscope uses stochastic super-resolution techniques (e.g., is a stochastic super-resolution microscope). In some embodiments, the stochastic super-resolution techniques use chance to improve emitter localization (e.g., by providing a flux such that only one emitter in a region is stochastically activated). In some embodiments, the super-resolution microscope is a stochastic optical reconstruction microscopy (STORM) microscope. In some embodiments, the stochastic super-resolution technique is direct stochastic optical reconstruction microscopy (dSTORM), photoactivated localization microscopy (PALM), fluorescence photoactivated localization microscopy (FPALM), spectral precision distance microscopy (SPDM), localization microscopy (e.g., single molecule localization microscopy (SMLM)), cryogenic optical localization in three dimensions (COLD), DNA-PAINT, or the like.In some embodiments, super-resolution microscopy or multiplexing methods described in Jungmann et al.

[0055] To quantify extracellular proteins, the observed fluorescence intensity can be normalized using the intrinsic molecular brightness of a single fluorophore attached to the antibody. This can be done by labeling double strands of DNA with a single fluorophore and attaching these at low concentration to a small area of the coverslip used for imaging, ensuring that single molecules are appropriately spaced. During imaging, an image is acquired in the small area using the same parameters as those used to image the cell, and the single molecule intensity from this area is used to calibrate the intensity acquired in the image of the rest of the cell.
[0056] In some embodiments, the super-resolution microscope can be configured to capture time series images of a sample. For example, a sample can be contacted with an antibody and imaged over time to obtain a time series of cellular characteristics. In this example, the time resolved data of the cellular characteristics can provide further data regarding the mechanism of action of the treatment as well as efficacy. In some embodiments, the imaging includes tracking the therapeutic agent, cellular characteristic, or cell surface receptor for a period of at least about 0.001, 0.005, 0.01, 0.05, 0.1, 0.5, 1, 5, 10, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000, 5,000, 10,000, 50,000 milliseconds or more.

MINFLUX is a super-resolution fluorescence microscopy that can provide resolution in the 1-3 nanometer (nm) range by localizing individual switchable fluorophores with a probing donut-shaped excitation beam (see, e.g., "MINFLUX nanoscopy delivers 3D multicolor nanometer resolution in cells" by Gwosch et al., Nature Methods, vol. 17, pp. 217-220, February 2020). In some embodiments, the super-resolution microscope uses stochastic super-resolution techniques (e.g., is a stochastic super-resolution microscope). In some embodiments, the stochastic super-resolution technique uses chance to improve emitter localization (e.g., by providing a flux such that only one emitter in a region is stochastically activated).

[0070] To quantify extracellular proteins, the observed fluorescence intensity can be normalized using the intrinsic molecular brightness of a single fluorophore attached to the antibody. This can be done by labeling double strands of DNA with a single fluorophore and attaching these at low concentration to a small area of the coverslip used for imaging, ensuring that single molecules are appropriately spaced. During imaging, an image is acquired in the small area using the same parameters as those used to image the cell, and the single molecule intensity from this area is used to calibrate the intensity acquired in the image of the rest of the cell.
[0071] In some embodiments, the super-resolution microscope can be configured to capture time series images of a sample. For example, a sample can be contacted with an antibody-based therapy and imaged over time to obtain a time series of cellular characteristics. In this example, time resolved data on cellular characteristics can provide further data on the mechanism of action of the therapy as well as efficacy.

In some embodiments, the stochastic super-resolution technique is direct stochastic optical reconstruction microscopy (dSTORM), photoactivated localization microscopy (PALM), fluorescence photoactivated localization microscopy (FPALM), spectral precision distance microscopy (SPDM), localization microscopy (e.g., single molecule localization microscopy (SMLM)), cryogenic optical localization in three dimensions (COLD), DNA-PAINT, or the like.In some embodiments, the super-resolution microscopy or multiplexing methods described in Jungmann et al.

[0139] To quantify extracellular proteins, the observed fluorescence intensity can be normalized using the intrinsic molecular brightness of a single fluorophore attached to the antibody. This can be done by labeling double strands of DNA with a single fluorophore and attaching these at low concentration to a small area of the coverslip used for imaging, ensuring that single molecules are appropriately spaced. During imaging, an image is acquired in the small area using the same parameters as those used to image the cell, and the single molecule intensity from this area is used to calibrate the intensity acquired in the image of the rest of the cell.
[0140] In some embodiments, the super-resolution microscope can be configured to capture time series images of a sample. For example, a sample can be contacted with an antibody-based therapy and imaged over time to obtain a time series of cellular characteristics.

23. The method of claim 22, wherein the antibody is an immune cell engager.
24. The method of claim 1, wherein the database of imaged cell characteristics is imaged at a resolution of at least about 50, about 40, about 30, about 20, about 10, about 9, about 8, about 7, about 6, about 5, about 4, about 3, about 2, or about 1 nanometer.
25. The method described in claim 1, wherein the database of imaged cell characteristics is imaged at (a) single molecule resolution or (b) single fluorophore resolution.
26. The method of claim 1, wherein the database of imaged cell characteristics is imaged in a high-throughput format.
27. The method described in claim 1, wherein multiple cellular characteristics are imaged (a) approximately simultaneously, (b) sequentially, or (c) some approximately simultaneously and the rest sequentially.
28. The method described in claim 27, wherein the multiple cell characteristics are on the surface of multiple cells.
29. The method of claim 2, wherein the extracellular molecule is (a) a membrane-bound protein, a membrane-bound ligand, or a protein or ligand bound to a membrane protein, or (b) selected from a protein ligand, a sugar, a lipid, a ligand, an extracellular receptor, a membrane-bound protein, a soluble protein, a structural protein, and a protein or ligand bound to a membrane protein.
30. A method described in any one of claims 1 to 29, further comprising a step of determining the local affinity (Kd) for binding of the antibody and correlating it with at least one cellular characteristic of the cells stored in the database.
31. A computer system for generating a database containing cellular characteristics from diseased and non-diseased cells, comprising: one or more processors; One or more memories having computer-executable instructions stored thereon, the computer-executable instructions, when executed, causing the computer system to receiving one or more images of the sample contacted with the antibody using a super-resolution microscope; generating a database comprising at least one cellular characteristic of cells in said sample; one or more memories for determining whether the at least one cellular characteristic is indicative of a cell in the diseased state or a cell in the non-disease state; A computer system comprising:
32. A non-transitory computer-readable medium having stored thereon computer-executable instructions that, when executed by one or more processors, cause a computer to receiving one or more images of the sample contacted with the antibody using a super-resolution microscope; generating a database comprising at least one cellular characteristic of cells in said sample; determining whether said at least one cellular characteristic is indicative of said diseased state cell or said non-disease state cell; Non-transitory computer-readable medium.
