Abstract： 目的构建乙型肝炎表面抗原(HBsAg)逆转录病毒表达质粒并探讨其在真核细胞中的表达.方法用限制性内切酶从重组质粒pBKS-S中切出HBsAg基因,并亚克隆到逆转录病毒表达质粒pLXSN,构建成重组质粒pLXSN-S;经限制性内切酶消化和DNA序列测定鉴定无误后,用阳离子脂质体转染法将重组质粒pLXSN-S分别转染HepG2、K562和EB病毒转化B淋巴母细胞(EBVC);用ELISA法检测HBsAg在细胞培养上清中的表达.结果经酶切和DNA序列测定鉴定证实重组质粒构建正确;质粒pLXSN-S转染细胞培养上清均可检测到HBsAg.结论逆转录病毒表达质粒pLXSN-S构建成功并可在真核细胞中稳定表达.
