摘要
目的建立犬狂犬病毒抗体ELISA检测方法。方法采用RV-CTN株感染Vero细胞制备狂犬病毒抗原,并经浓缩和纯化后,分别建立间接ELISA和竞争ELISA方法。结果经初步质量鉴定,特异性10份阳性,20份阴性,符合率均达100%,间接ELISA的灵敏度达1∶640,竞争ELISA达1∶32;间接ELISA的精密性(变异系数CV)为6.98%,竞争ELISA为5.10%。结论建立了用间接ELISA检测抗狂犬病毒IgG抗体和竞争ELISA检测抗狂犬病毒总抗体的方法,并生产出相应试剂盒。
Objective Establishing the methods of detecting the rabies virus IgG antibody with the indirect ELISA and the total antibody with competitive ELISA. Methods Rabies virus antigen was prepared with Vero-cell infected by RV-CTN, which was concentrated and purrificated, and indirect ELISA and competitive ELISA were established. Results Quality appraisal showed that the specificity accord ratio of the 10 positive and 20 negative samples, was 100% ; and the sensibility of indirect ELISA was 1： 640, the competitive ELISA was 1： 32 ; the preciseness （ Variability Coefficient, CV） of the indirect ELISA was 6.98%, and the competitive ELISA was 5.10%. Conclusion This research established successfully the methods of detecting the rabies virus IgG antibody with the indirect ELISA and the total antibody with competive ELISA, and the reagent cases were produced.
