摘要:

旨在比较检测小反刍兽疫抗体的间接ELISA和竞争ELISA方法,通过诱导表达小反刍兽疫病毒(PPRV)N蛋白,并以此作为包被抗原,检测94份绵羊和25份山羊血清样本。结果显示间接ELISA与标准竞争ELISA试剂盒的符合率为74.8%,竞争ELISA与标准竞争ELISA试剂盒的符合率为96.6%。竞争ELISA比间接ELISA方法检测结果可信度高,适于临床推广应用。

Abstract:

The indirect ELISA and the competitive ELISA method were compared in the detection of serum antibody against Peste des Petits Ruminants Virus (PPRV).The PPRV N protein to be used as a coating antigen was expressed in BL21 and purified by Ni Sepharose FF column.Ninety-four sheep and twenty-five goats serum samples were detected by the ELISA methods based on the recombinant N protein.The coincidence rate of the indirect ELISA and the competitive ELISA kit was 74.8%,the coincidence rate of the competitive ELISA and the competitive ELISA kit was 96.6%.The detection results showed that the competitive ELISA is more reliable than the indirect ELISA method, and the competitive ELISA is suitable for clinical application.
