摘  要:
参照GenBank公布的鹅源新城疫病毒NA-1株F基因(DQ659677)的核苷酸序列设计1对引物,通过PCR扩增F基因全长,将其克隆到pET-22b(+)载体中,构建了原核表达载体pET-22b(+)-F,转化大肠杆菌BL21(DE3),表达并纯化了重组蛋白,Western-blot证明该重组蛋白具有免疫原性。利用重组蛋白为包被抗原,通过方阵试验确定了包被抗原的最佳包被量为0.21μg/孔,建立了检测鹅源新城疫病毒抗体的间接ELISA诊断方法。

摘  要:
According to the F gene sequences of Newcastle disease virus from goose(DQ659677) available in GenBank,a pair of primers was designed for F gene of NDV from goose.Then the amplified product was cloned into prokaryotic expression vector pET-22b(+) and over-expressed in E.coli BL21(DE3).Western-blot analysis showed that the purified recombinant protein had good immunological activity.The optimal concentration of coated antigen F recombinant protein was 0.21 μg per well,which was determined by phalanx titrimetry.Then an indirect ELISA was established for detection of the antibody against Newcastle disease virus from goose.
