摘  要:
将猪带绦虫六钩蚴10 ku蛋白(TSO10)和囊尾蚴10 ku蛋白(CE10)的基因克隆到表达载体中,构建重组表达载体pGEX-4T-TSO10和pGEX-4T-CE10,经测序证明基因序列完全正确。重组表达载体转化大肠杆菌后诱导表达,用SDS-PAGE、Western-blot和薄层扫描检测表达产物。表达的目的蛋白纯化后用于血清样品ELISA检测。SDS-PAGE、Western-blot和薄层扫描检测结果表明,六钩蚴和囊尾蚴10 ku蛋白基因均能在大肠杆菌中成功表达,表达的融合蛋白的相对分子质量约为35 ku,并能被囊虫病人阳性血清所识别,具有反应原性,表达量分别占菌体蛋白总量的25%和30%。ELISA检测结果显示,10 ku蛋白可用于囊虫病的诊断。

摘  要:
Recombinant expression plasmids,designated as pGEX-4T-TSO10 and pGEX-4T-CE10,were constructed by insertion of the TSO10 gene from Taenia solium oncosphere and the CE10 gene from the larva,respectively,and identified by sequencing.The results of SDS-PAGE,Western-blot and lamellar scanning showed that both fusion target proteins expressed in E.coli were 35 ku in molecular weight and can be recognized by the positive serum from a cysticercosis patient,and that their contents accounted for 25% and 30% of total bacteria proteins,respectively.Furthermore,the results of ELISA indicated that the recombinant proteins are suitable for diagnosis of cysticercosis.
