【摘要】:为优化狂犬病病毒G蛋白的原核表达条件,探究其反应原性,参照狂犬病病毒CTN-1V10株编码G蛋白基因序列,采用生物工程合成的方法合成编码G蛋白的基因片段,并将该片段命名为G5F。将该片段与pET-28a原核表达载体连接,构建重组表达质粒pET-G5F,并将重组质粒进行诱导表达,在IPTG浓度为0.2 mmol/L、温度为20℃、诱导12 h时,重组蛋白表达量最高。SDS-PAGE电泳及Western blot分析表明,G5F重组蛋白可溶性表达量高,且可以被抗狂犬病病毒单克隆抗体识别,反应原性良好。
[Abstract]:In order to optimize the prokaryotic expression conditions of rabies virus G protein and to explore its reactivity, the gene fragment encoding G protein was synthesized by bioengineering method according to the coding G protein gene sequence of rabies virus CTN-1V10 strain. The fragment was named G5F. The recombinant plasmid pET-G5F was constructed by ligating the fragment with the prokaryotic expression vector pET-28a. The recombinant plasmid was induced to express at 0.2 mmol / L IPTG at 20 鈩,
