Definitions
- the invention belongs to a biological detection method, in particular to a method for detecting silver-proteins Ag-NORs in the nucleolar forming region of lymphocytes.
- the detection in the prior art is only used for tissue sectioning.
- the subject must first perform surgery and take biopsy for staining examination.
- the patient suffers a lot and it is not appropriate to repeat the examination.
- the invention adopts a new detection object, that is, the detection of T-lymphocytes in peripheral blood, overcomes the shortcomings in the prior art, and provides a T-cell with a small blood volume, simple operation, simple process and easy to popularize. Detection of Ag-NORs in the nucleolar forming region of lymphocytes.
- the method for detecting Ag-NORs in the T-lymphocyte nucleolar formation region of the present invention includes five parts: cell culture, cell separation, cell preparation, staining, and detection.
- composition of the culture solution and the amount of 1000 grams of culture solution are:
- LG L-glutamine
- PHA phytohemagglutinin
- fetal bovine serum 100-300ml penicillin (800,000 u / 2ml) 0. 1- 0. 5ml streptomycin ( 1 million u / 2ml) 0. 1— 0. 5ml
- the rest is made up with distilled water.
- the pH of the culture broth is 6. 5-7.
- the culture solution is prepared by the following methods and steps:
- step 3 Add L-glutamine, sodium heparin, phytohemagglutinin (PHA), penicillin, and streptomycin to the solution in step 2 and mix thoroughly until all are dissolved.
- PHA phytohemagglutinin
- T-lymphocyte culture was performed as follows:
- hypotonic solution is a 0.43% sodium chloride solution
- the fixing solution is a mixed solution of methanol and glacial acetic acid in a ratio of 3: 1 by volume.
- the dyeing liquid is composed of liquid A and liquid B.
- the composition of liquid A and its ratio are: 30-60 g of nitric acid (analytical grade) and 100 ml of distilled water.
- the preferred ratio of liquid A is: 50 g of silver nitrate (analytical grade) and 100 ml of distilled water.
- Solution A is prepared by adding silver nitrate to distilled water in proportion, stirring thoroughly until it is completely dissolved, and storing it in a brown bottle at 2-8 ° C.
- composition and composition of liquid B are: 1 to 3 g of gelatin, 200 to 50 g of pure acetic acid (100 liters, 100 ml of distilled water.
- the preferred ratio of liquid B is: 2 g of gelatin, 250 microliters of formic acid, and 100 ml of distilled water.
- the preparation method of the liquid is: adding formic acid to distilled water, mixing, adding gelatin, mixing uniformly, and then incubating at 37 ° C or at room temperature until completely dissolved, to obtain the liquid B of the present invention. — 8 Saved.
- all the utensils and other utensils used need to be disinfected and sterilized, and all operations should conform to the aseptic operation.
- the methods of disinfection and sterilization and aseptic operation methods are well known in the art technology.
- the blood volume is small, and only 0.4 to 0.5 ml of blood is required for the testicle, while the prior art generally requires 5 to 10 ml;
- the cell culture method is convenient, time-saving, easy to operate, and simple in equipment.
- lymphocyte separation solution was used for lymphocyte separation, and a relatively expensive carbon dioxide incubator was required. The operation was tedious, time-consuming, and expensive. .
- the dyed specimens are stable in color and will not fade in 1 to 2 months under dry conditions at room temperature.
- the method for detecting Ag-NORs in the nucleolar formation region of T-lymphocytes in this embodiment includes five parts: cell culture, cell separation, cell preparation, staining, and detection.
- the pH of the culture broth is 7.0 to 7.2.
- T-lymphocyte culture is performed according to the following methods and steps:
- the T-lymphocyte conversion rate is over 80%, and the nucleus enlarges and the nucleoli divides.
- hypotonic solution is a 0.43% sodium chloride solution
- the fixing solution is a mixed solution prepared by methanol and glacial acetic acid in a volume ratio of 3: 1.
- Liquid A silver nitrate (analytical grade) 50g, distilled water 100ml;
- Solution B 2g gelatin, 340 microliters of formic acid, and 100ml of distilled water.
- T-lymphocyte staining was performed as follows:
- the above-mentioned stained slides were read in a KL-type tumor immune image analysis system (developed and produced by Beijing Jianerkang Medical Equipment Co., Ltd.), and 30-50 cells were analyzed. The average value is used as a quantified value.
- composition and ratio of liquid B of the dyeing liquid used in this embodiment are: 2 g of gelatin, 250 g of gallic acid, 100 ml of distilled water.
- the remaining reagents, steps and conditions are the same as those of the first embodiment.
