Abstract: | Abstract: Objective To develop a ELISA method for determination of Sendai virus( SeV) antibody in Mongolian gerbil. Methods Hatchs chicken embryos,vaccinate the Sendai Virus,prepare the normal chicken embryo allantoic fluid antigen and special SeV antigen,titrate the best working density of enzyme union and the normal or special antigen and carry out the experiments of specificity,sensitivity,accuracy and stability. Result The best working density of normal,special antigen and the enzyme union is 0. 1 μg /mL,2 μg /mL and 1 ∶ 5 000 respectively; The inter-assay coefficient of variation of normal antigen and special antigen is 9. 6% and 8. 4% respectively,the intra-assay average coefficient of variation is 9. 0% and 5. 9% respectively; The detection sensitivity is 1∶ 10 240; There is no cross-reactivity with mouse hepatitis virus( MHV) ,Pneumonia virus of mice ( PVM) ,and Reovirus type 3. The stability test shows the relative deviation is below 25%. Conclusion TheELISA method is good in specificity,sensitivity,duplication,and stability,as a result of which ELISA can be used in detecting the Sendai virus antibody. |
