T载体克隆乙肝病毒preS2+S基因的实验研究
Study on construction of eukaryotic expression plasmid encoding hepatitis B virus preS2+ S gene with T vector
【摘要】 将商品化真核表达载体pcDNA3改造成T载体pcDNA3-T,并运用pcDNA3-T直接克隆了由PCR扩增的adw2亚型乙肝病毒preS2与S基因。结果:pcDNA3-T与PCR产物的重组率高达70%。提示:该方法具有简便,省时等特点。
【Abstract】 In this study, a commerciallzed eukaryotic expression vector pcDNA3 was modified to produce T vecor pcDNA3 - T,which was directly applied to cloning of preS2 + S gene of adw2 subtype hepatitis B virus.The results showed that pcDNA3-T was efficiently recombined with PCR products, and the novel method was time saving and convenient.
