小反刍兽疫病毒M蛋白主要抗原表位区的原核表达及鉴定
Prokaryotic expression and identification of M protein main epitopes of peste des petits ruminants virus
摘要
Abstract
To prepare peste des petits ruminants virus(PPRV)-specific monoclonal antibody and monitor the clinical antibody level of PPRV, putative B-cell linear epitope sites of M protein of PPRV Nigeria75/1 strain was analysed by online software. A pair of primers was designed to amplify a 303 bp targeting gene fragment which was then cloned into the prokaryotic expression vector pET-32a( + ). The re-combinant protein was expressed in Escherichia coli BL21(DE3) by IPTG induction and purified. SDS-PAGE showed that the recombinant was expressed in the solube form with high expression level and Western-blot analysis indicated that the purified M protein possessed good reactinogenicity. The expressed M protein could be used for the preparation of specific monoclonal antibodies and surveillance of antibody level of PPRV.关键词
