摘  要:
本试验将成功克隆的牛病毒性腹泻-黏膜病病毒Changchun184株E2基因与大肠杆菌-分枝杆菌整合表达载体pMV361连接,构建重组整合质粒pMV361-E2。并确定了电转化的最佳条件:2.0 kV/cm、25μF、1 000Ω,成功获得了E2基因重组卡介苗。在45℃下热诱导E2基因在重组卡介苗中的表达,通过SDS-PAGE电泳和免疫印迹检测,结果显示,在44 kD处出现目的条带,符合E2基因表达蛋白的大小,表明牛病毒性腹泻-黏膜病病毒E2基因在卡介苗中成功表达。

摘  要:
E2 gene of BVDV Changchun 184 strain was cloned and inserted into the integration expression plasmid vector p MV361,and the recombinant integration plasmid p MV361-E2 was constructed.Then p MV361- E2 was transformed into BCG successfully and recombinant BCG resistive to kanamycin was obtained. After studying the main factors which can effect the result of electroporation,the optimal electroporation parameters were confirmed,which are 2.0 kv/cm,25 μF,and 1 000 Ω.The resulting plasmids p MV361-E2 was electrotransfected into BCG that it was induced at 45 ℃,and then the SDS-PAGE and western blotting were used to analyze the expression product. Our results showed that the vector p MV361 containing E2 gene was successfully constructed,and Western blotting indicated that the E2 gene was successfully expressed in rBCG.
