摘要: 本研究利用原核表达的小反刍兽疫病毒核衣壳(N)蛋白作为标准抗原蛋白,建立PPRV抗体检测方法,同时对建立的检测方法的相关条件进行了优化。通过优化确定抗原的最佳包被浓度为10 mg/L,血清最佳稀释度为1∶40,二抗的使用浓度为1∶200,血清及二抗的最佳反应条件为37 ℃孵育60 min,底物的最佳反应时间为37 ℃ 15 min。通过批内及批间重复性的评价,变异系数均小于0.1,表明本检测方法具有较高的可重复性。经过临床样品检测证明,建立的检测方法可用于临床PPRV抗体的检测。

Abstract: This study established an indirect antibody enzyme-linked assay system based on the nucleocapsid (N) protein of peste des petits ruminants virus(PPRV).We optimized some factors such as antigen coating concentration (10 mg/L),the dilution of serum was 1∶40,the work concentration of HRP-labeled anti-goat IgG(1∶200),reacted conditions of samples and HRP-labeled anti-goat IgG(37 ℃,60 min).The CV is not beyond 0.1.The developed method is suitable for PPRV monitoring and detection,especially for screening large number of samples in farms.

Key words: peste des petits ruminants virus(PPRV); nucleocapsid protein; prokaryotic expression; indirect ELISA
