[0002] Multiple myeloma (MM) is a malignant plasma cell hematological tumor. Its tumor cells originate from plasma cells in bone marrow, and plasma cells, also known as effector B cells and antibody-secreting cells, are terminal differentiated cells differentiated from B cells under antigen stimulation. WHO classifies it as a kind of B cell lymphoma, called plasma cell myeloma / plasma cell tumor. B cell maturation antigen (BCMA) or CD269, also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF-17), has high level of restricted expression in normal and malignant plasma cells (PC), and is currently a popular ideal target antigen for new MM treatment. In a mouse model, BCMA overexpression can significantly promote the in vivo growth of xenotransplant MM cells, and in addition, studies have shown that the higher the BCMA level, the worse the prognosis, indicating that BCMA is a useful biomarker for MM disease activity and prognosis.

[0058] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0059] Please see Figures 1 to 4It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0060] This invention provides a kit for detecting antigen expression in plasma cell tumors, such as... Figures 1-4 As shown, the device includes an outer box 1 and an inner module 2. The outer box 1 has a sample chamber 11 and an insulation chamber 12 from top to bottom. The sample chamber 11 is hollow and open at the top. The bottom of the sample chamber 11 has several sample storage holes 13. The insulation chamber 12 is hollow and open on one side. The inner module 2 is detachably nested in the hollow area of ​​the sample chamber 11. The inner module 2 includes an antibody module 21 and a universal reagent module 22 that are detachably connected in the horizontal direction. The antibody module 21 has several antibody storage holes 23, and the universal reagent module 22 has several universal reagent storage holes 24. A box cover 3 is also connected to the adjacent non-opening sides of the insulation chamber 12. The box cover 3 can be opened to close the hollow area of ​​the sample chamber 11 where the inner module 2 is detachably nested.

[0061] In the above kit, such as Figures 1-4 As shown, the sample storage hole 13 penetrates the bottom of the sample chamber 11 and communicates with the insulated chamber 12. It is used to securely hold test tubes containing samples, facilitating independent sample incubation. The sample is a pretreated, fresh leukocyte suspension.

[0062] In the above kit, such as Figure 1 , 2 As shown in Figure 4, the insulated chamber 12 contains insulating material. This material is used to keep the samples stored in the sample storage holes 13 of the sample chamber 11 warm, ensuring that samples with special temperature requirements can also be tested conveniently and accurately using this kit. The insulating material includes, but is not limited to, biological ice packs. The insulating material can be inserted and removed through the side opening of the insulated chamber 12.

[0063] In the above kit, such as Figure 1As shown, the vertical height of the inner module 2 is not less than the depth of the sample chamber 11.

[0064] In the above kit, such as Figure 3 As shown, the sides of the antibody module 21 and the universal reagent module 22 that are in contact with each other are respectively provided with a first connector 41 and a second connector 42, and the first connector 41 and the second connector 42 are detachably connected. This facilitates the handling and transfer of the antibody module 21 and the universal reagent module 22. For example, in the experimental stage, the antibody module 21 can be removed separately and stored in a light-proof environment.

[0065] In one embodiment, the detachable connection between the first connector 41 and the second connector 42 is a detachable magnetic connection. That is, both the first connector 41 and the second connector 42 are connectors containing magnets, and are connected by magnetic attraction between the magnets.

[0066] In the above kit, such as Figure 3 As shown, the antibody module 21 has fillable strips 25 on its side. These fillable strips 25 are tabular strips with borders, and the grids can be filled with color. They are used for recording and managing reagent usage. Specifically, one strip is filled for each person's dose of reagent used to record the antibody usage, facilitating reagent inventory management and early warning.

[0067] In one implementation, such as Figure 3 As shown, the fillable strip 25 is disposed on the side not connected to the antibody module 21 and the general reagent module 22.

[0068] In the above kit, such as Figure 3 As shown, a barcode strip 26 is provided on the side of the universal reagent module 22. The barcode strip 26 is a conventionally used, scannable barcode for managing reagent scanning information. Specifically, the barcode strip 26 integrates the reagent kit's inventory information and expiration date. After scanning, it connects to the reagent management software to achieve electronic record management of reagent information and status.

[0069] In one implementation, such as Figure 3 As shown, the barcode strip 26 is located on the side that is not the connection between the general reagent module 22 and the antibody module 21.

[0070] In the above kit, such as Figure 3 As shown, a reagent bottle for storing antibody reagents is snapped into the antibody storage hole 23. The antibody reagents include, but are not limited to, antibodies MICA / MICB, BCMA, CD138, CD38, CD56, CD19, CD45, etc.

[0071] In the above kit, such as Figure 3As shown, a reagent bottle for storing general reagents is snapped into the general reagent storage hole 24. The general reagents include, but are not limited to, hemolysin, PBS buffer, etc.

[0072] The aforementioned inner module 2 stores reagents through the antibody storage port 23 of the antibody module 21 and the universal reagent storage port 24 of the universal reagent module 22. This structure allows users to easily retrieve reagents according to experimental procedures, reducing the risk of reagent mix-ups, and flexibly storing antibody reagents that require proper light protection. Furthermore, during the addition of universal reagents or incubation, the antibody module 21 can be stored separately in a light-protected environment, ensuring the stability and integrity of reagent placement throughout the retrieval and storage process.

[0073] In the above kit, such as Figure 4 As shown, the box cover 3 includes a first box cover 31 and a second box cover 32; the first box cover 31 includes a first cover segment 311, a second cover segment 312, and a third cover segment 313 connected in sequence and foldable. The first cover segment 311 is connected to the opposite side of the opening side of the heat preservation chamber 12, and the second cover segment 312 can be opened to close the hollow area of ​​the sample chamber 11 where the inner module 2 is detachably nested. The third cover segment 313 can be opened to close the opening side of the heat preservation chamber 12; the second box cover 32 includes a fourth cover segment 321, a fifth cover segment 322, and a sixth cover segment 323 connected in sequence and foldable. The fourth cover segment 321 is connected to the adjacent side of the opening side of the heat preservation chamber 12, and the fifth cover segment 322 can be opened to close the hollow area of ​​the sample chamber 11 where the inner module 2 is detachably nested. The sixth cover segment 323 can be opened to close the opposite side of the heat preservation chamber 12 where the fourth cover segment 321 is connected. The first lid 31 and the second lid 32 mentioned above can form a cross lid, and when the outer box 1 is used alone, it can form an independent light-proof space required for antibody incubation.

[0074] In one implementation, such as Figure 4 As shown, the third cover section 313 is provided with a third connector 43 on the side facing the outer box 1, and the sample chamber 11 and the heat preservation chamber 12 are provided with a fourth connector 44 on the same side of their openings. The third connector 43 and the fourth connector 44 are detachably connected.

[0075] In a preferred embodiment, the detachable connection between the third connector 43 and the fourth connector 44 is a detachable magnetic connection. That is, both the third connector 43 and the fourth connector 44 are connectors containing magnets, and are connected by magnetic attraction between the magnets.

[0076] In one implementation, such as Figure 4As shown, a fifth connector 45 is provided on the side of the sixth cover section 323 facing the outer box 1, and a sixth connector 46 is provided on the sample chamber 11 on the same side as the side on which the heat preservation chamber 12 is connected to the fourth cover section 321. The fifth connector 45 and the sixth connector 46 are detachably connected.

[0077] In a preferred embodiment, the detachable connection between the fifth connector 45 and the sixth connector 46 is a detachable magnetic connection. That is, both the fifth connector 45 and the sixth connector 46 are connectors containing magnets, and are connected by magnetic attraction between the magnets.

[0078] The aforementioned lid 3, in conjunction with the outer box 1, secures the inner module 2, which is detachably nested within the hollow area of ​​the sample chamber 11, ensuring that all reagents remain stable and upright during reagent kit transportation. Simultaneously, the outer box 1 can also serve as a suitable and independent antibody incubation device for experiments. Furthermore, the tri-fold lid 3, connected to the adjacent non-opening sides of the insulated chamber 12, creates an independent, light-protected space for antibody incubation when the outer box 1 is used alone.

[0079] The following is combined Figures 1-4 This describes the specific usage process of a kit for detecting antigen expression in plasma cell tumors according to the present invention.

[0080] Operator obtains such Figures 1-4 When using a kit for detecting antigen expression on plasma cell tumors, the first lid 31 and the second lid 32 ensure that the reagents in the outer box 1 and inner module 2 remain stable and intact during storage and handling. By storing the kit as a whole and not mixing it with other antibodies, the instability of the results caused by reagent issues can be effectively avoided.

[0081] Open the first and second cover 31 and 32 of the cross-over box to detach the third connector 43 from the fourth connector 44 and the fifth connector 45 from the sixth connector 46. Remove the inner module 2 from the sample chamber 11 of the outer box 1. Following the experimental steps, take out the corresponding reagents from the antibody storage well 23 of the antibody module 21 and the universal reagent storage well 24 of the universal reagent module 22 for the experiment. The specific operation is as follows: Separate the first connector 41 and the second connector 42 to separate the antibody module 21 and the universal reagent module 22. Place the antibody module 21 in the refrigerator for use in the next step. Take out the outer box 1 of the reagent kit and the universal reagent module 22 and place them on the work surface. During this step, verify the reagent status (expiration date, quality control status) on the barcode strip 26 of the universal reagent module 22 and record the number of uses on the refillable strip 25 with a marker (record the number of uses corresponding to the number of antibody doses required this time). Invert and mix the sample to be tested (prepared leukocyte suspension). Add PBS buffer from universal reagent module 22 to the sample tube until it is about 3 / 4 full. Centrifuge at 1500 rpm for 5 min, discard the supernatant, and repeat the process twice. Resuspend the cells in PBS buffer to 1 mL and set aside. Remove antibody module 21 from the refrigerator and take out the antibody reagent from reagent storage well 23. Prepare a flow cytometry tube and label it with the specimen number. Add single-person antibody to the flow cytometry tube in sequence, and add 100 μL of washed sample. Mix well and incubate for 15 min in the dark. After incubation, add 1 mL of hemolysin to the flow cytometry tube, mix well, and incubate again at room temperature in the dark for 10 min. The above steps use the incubation device of this kit for low-temperature incubation in the dark: place a low-temperature biological ice pack through the side opening of the incubation chamber 12 as insulation material. This protects the state of the samples and antibody activity in the sample storage well 13 and antibody storage well 23, ensuring the stability and accuracy of plasma cell-associated antigen expression levels. The prepared flow cytometry tubes are attached to the sample storage well 13. The first and second lids 31 and 32 are then overlapped on the sample chamber, forming a clean, light-proof, and low-temperature incubation environment with the sample chamber 11. This is achieved through the triple-fold structure of the first lid 31 (first section 311, second section 312, and third section 313) and the second lid 32 (fourth section 321, fifth section 322, and sixth section 323). Simultaneously, the third connector 43 is connected to the fourth connector 44, and the fifth connector 45 is connected to the sixth connector 46. This creates an independent, clean, light-proof, and low-temperature incubation environment. The first connector 41 and the second connector 42 of the reagent module 21 are then connected and stored together in a refrigerator. This ensures that the temperature and ease of reagent access are met, while also maintaining overall integrity and preventing mixing with other antibodies, thus avoiding instability in the results caused by reagent issues. After incubation, 5 drops of PBS buffer are added to the flow cytometry tubes and mixed well. The samples are then analyzed within 12 hours.

[0082] This kit contains antibody reagents BCMA and MICA / MICB corresponding to specific antigens of plasma cell tumor progression and immune status, as well as antibody reagents required for accurate plasma cell population differentiation. These antibodies are flexibly integrated through antibody module 21, and the stability of sample status and plasma cell tumor antigen expression is ensured through a low-temperature incubation environment. It can not only accurately distinguish plasma cells using flow cytometry software, but also simultaneously and accurately assess the expression of specific antigens. It can be used for disease progression and prognostic assessment of plasma cell tumors, as well as related research on immune status.

[0083] In summary, the kit provided by this invention for detecting antigen expression in plasma cell tumors avoids antibody misuse, exhibits good stability and integrity during storage and handling, provides a light-protected environment, and ensures the storage of temperature-sensitive samples. The above embodiments are merely illustrative of the principles and effects of this invention and are not intended to limit it. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this invention should still be covered by the claims of this invention.
