摘要
本文采用聚合酶链反应(PCR)方法从9例抗-HBe阳性的乙肝患者血清中扩增了含PreC和C基因的DNA片段,并分别与载体pUC18相连接,成功地克隆入大肠杆菌中,为后续的DNA测序及分析PreC基因突变打下了基础。并建立了快速、简便的PCR直接筛选和鉴定阳性克隆的方法。
For the purpose of analysing HBV PreC gene mutations,a
specific HBV DNAfragment including PreC and C gene was amplified by PCR from the sera of 9
patients posi-tive for Anti-HBe,and cloned into the vector pUC18.A simple and rapid method for
screen-ing positive clones by PCR was also established in this paper.
