This standard was mainly drafted by Da He Shanming. This standard was first issued in January 1994. National Standard of the People's Republic of China Laboratory Animals Sendal virus detection method Laboratory animal Method for esamination of Sendal virus (SV) This standard specifies the detection method and reagents of Sendal virus (SV). This standard is applicable to the detection of Sendal virus in Tibetans, Tibetans, guinea pigs, hamsters and rats. Reference Standards GB/T14926-23-2001 GB/T14926.23-1994 The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised. All parties using this standard should discuss the possibility of using the latest version of the following standards. GB/T14926.50-2001 GB/T14926.51—2001 GB/T 14926.52-2001 GB/T14926.54—2001 Laboratory animals Laboratory animals Laboratory animals Laboratory animals Enzyme-linked immunosorbent assay Immunotoxicity test Immunofluorescence test Hemoglobin inhibition test According to the principle of immunology, SV antigen is used to detect Sendai virus antibodies in the sera of mice and rats: or according to the principle that SV can absorb erythrocytes of chickens and rats under certain conditions, and this ability of erythrocytes can be inhibited by specific antibodies , detect Sendai virus antibodies in mouse, rat, guinea pig, and hamster immune sera. Main reagents and equipment 4.1 Reagents: 4.1-1 ELISA antigen 4.1.1-1 Specific antigen Infect 9d SPF chickens with SV and press the allantoic cavity. Culture in a 36℃ incubator. After 72h, freeze at 4℃+ and collect the allantoic fluid aseptically the next day. Centrifuge at 4℃2000r/min for 10min. Use 0.5% chicken or guinea pig red blood cells and SV positive serum to do hemagglutination and hemagglutination inhibition tests to verify its virus specificity and hemagglutination titer. The supernatant is then concentrated by ultracentrifugation to make ELISA antigen. 41.1-2 Normal antigen 9-day-old SPF chicken urine fluid. 4.1.2 Antigen slice SV infected BHK21 cells, 2~3 days after inoculation, when the lesions reached ++~+++, use lysate to digest and disperse, wash with PBS, and wash the slice. After drying at room temperature, fix with cold acetone for 10min-20c and store.
