Description
Technical Field
The utility model belongs to the technical field of the analysis and detection technique and specifically relates to a tumour somatic mutation site flow formula detection and analysis device.
Background
Flow Cytometry (FCM) is a modern cell analysis technology developed in the seventies, which integrates computer technology, laser technology, fluid mechanics, cytochemistry and cellular immunology, and has the functions of analyzing and sorting cells. The cell size and the properties of internal particles can be measured, the cell surface and cytoplasm antigens, the intracellular DNA and RNA content and the like can be detected, the group cells can be analyzed on the single cell level, a large number of cells can be detected and analyzed in a short time, data is collected, stored and processed, multi-parameter quantitative analysis is carried out, the cell size and the properties of internal particles can be measured, a certain subset of cells can be classified and collected, and the separation purity is higher than 95%. Flow cytometry is widely used in hematology, immunology, oncology, pharmacology, molecular biology and other disciplines.
The application of flow cytometry in hematology mainly relates to the immunophenotyping analysis of white blood cells, red blood cells, platelets and leukemia, myeloma and lymphoma cells, CD34+ cell counting, lymphocyte subpopulation and immune function detection, cell cycle and DNA ploidy analysis, apoptosis and other aspects. Immunofluorescence staining is a key step for performing cellular immune marker analysis by using a flow cytometer, and mainly comprises a direct immunofluorescence staining method and an indirect immunofluorescence staining method. The indirect immunofluorescence staining is to adopt a specific primary antibody without fluorescence labeling to react with a specimen to be detected, after hemolysis and washing, the primary antibody with fluorescence labeling is added, and after incubation and washing, the detection is carried out on a computer. The direct immunofluorescence staining is that a specific antibody connected with a fluorescent dye is added during marking, and the method has the advantages of simple operation, low background fluorescence, high signal-to-noise ratio, simultaneous marking of multi-color antibodies and the like, so that the method is widely applied to various laboratories at present and is a multi-color direct immunofluorescence marking method.
Immunofluorescence staining can be divided into cell surface and intracellular antigen staining, depending on the location of the labeled antigen. The cell surface antigen marker is mainly synthesized from the inside of cells and then expressed on the surface of cell membranes, and the flow cytometry phenotypic analysis experiment operation of various cell surface antigens or receptors is relatively simple, so that the cell surface antigen marker is most widely applied to clinical application. In addition to molecules expressed on the cell surface, a large number of molecules or cytokines to be secreted, etc., which play important physiological roles, are present in the cell. In contrast to the labeling of cell membrane surface antigen markers, labeling of intracellular or nuclear antigens and the measurement of intracellular cytokines first require a transmembrane process, and the experimental environment required for different antigen labeling is different. For example, in the case of cell surface antigen markers, intracellular or nuclear antigen markers, the fluorescent dye is incubated under "incubation in the dark at room temperature for 15 min", and in the case of intracellular cytokine staining, the fluorescent dye is incubated under "incubation in the dark at 4 ℃ for 30 min".
The fluorescent staining of single cell suspension is related to the accuracy of flow analysis, the characteristics and dose-effect relationship of the dye should be paid special attention, and the immunofluorescent staining also involves the problems of antibody specificity and titer, and should be carried out strictly according to the requirements of experimental operation. The rising of the environmental temperature has obvious influence on the fluorescent dyeing, the viscosity of the solution can be increased, the power of fluorescent dye molecules is increased, the possibility of fluorescent quenching is increased, and the photon yield of the fluorescent molecules is reduced. If the temperature is kept below 20 ℃, the change of photon yield is not influenced, and the light irradiation time of the dyed sample is reduced as much as possible, so that the fluorescence intensity during detection is not influenced.
In the sample preparation process for flow analysis, the requirements of the experimental environment on temperature are different according to different labeled antigen sites. After the sample is dyed by adding the fluorescent dye, the sample is placed in a dark environment for incubation, and the process from dyeing to the intermediate experimental step of on-machine inspection is reduced as much as possible, so that the light irradiation time of the dyed sample is reduced, and the fluorescent intensity during the inspection is not influenced. Currently, biological laboratories perform this operation on conventional test tube racks or flow tube racks, and in order to achieve the light-shielding effect, the test tube racks or flow tube racks containing samples need to be transferred to light-shielding places or containers, such as drawers, cabinets, and the like. If the experiment is required to be carried out in a temperature environment of 4 ℃, the test tube rack or the flow tube rack with the samples is also required to be transferred into a refrigerating chamber of a refrigerator. The above operations not only make the experiment operation more complicated, but also prolong the light irradiation time of the stained sample, increase the risk of quenching of fluorescent molecules, cause the distortion of the detection result, even cause the experiment failure, and seriously affect the subsequent research or clinical diagnosis.
In summary, it is very important to provide an experimental apparatus capable of providing a light-shielding and suitable temperature environment for flow cytometry analysis to obtain an accurate and effective flow detection result.
