According to the principles of immunology, MVM antigen is used to detect MVM antibodies in mouse serum. Main reagents and equipment
4.1 Reagents:
4.1.1 ELISA antigens
41.1-1 Specific antigens
MVM inoculated with mouse renal cell (ME) or 3T3 cells, maintained and cultured for 7~10 days, harvested when the cell lesions reached +++~++++. Freeze for three times or ultrasonic treatment, centrifuged at low speed to remove the lesions, and the supernatant was concentrated by ultracentrifugation to make ELISA antigens
4-1-1-2 Positive antigens
ME or 3T3 cells were freeze-thawed, and the supernatant was removed by low speed centrifugation to remove the lesions. 4-1.2 Antigen slices
MVM inoculated with rat renal cell (RE) or ME cells, cultured for 7~10 days. When the lesions reached +++~++++, they were digested and dispersed with trypsin, washed with PBS, and smeared. After drying at room temperature, they were fixed with cold acetone for 10 minutes and stored at -20°C. 4.1.3 Positive serum
Antiserum obtained by immunizing SPF mice with MVM antigen 4.1-4
Negative serum

Detection method
Use ELISA method (see GB/T14926-50-2001) for serological test. Use IFA method (see GB/T14926.52-2001) for serological test. Use IEA method (see GB/T14926.51-2001) for serological test. Result judgment
For positive test results, use the same method or another method to try again. If it is still positive, it is judged as positive. Result report
Make a report based on the judgment result.
