试验将编码狂犬病病毒糖蛋白、核蛋白融合基因克隆到原核表达载体pET-32a(+)中,构建狂犬病病毒原核表达质粒。将该质粒转化到大肠杆菌BL21中,经踟诱导表达出约2.09×10^4D的狂犬病病毒糖/核融合基因编码的蛋白质。Western—blotting检测结果表明,该融合蛋白质具有免疫原性。
The experiment was conducted to construct pmkaryotic expression plasmid containing the G and N melt genes of rabies virus through cloning the genes of rabies virus into pET-32a( + ). After transforming the plasmid into E. coli BL21, the bacteria were induced by IPTG and the protein was detected with western-blotting test. The result indicated that the two genes could be co-expressed by the pmkaryotic expression plasmid, which will supply foundation for the preparation of the antigen use to diagnose rabies.
