摘要
采用分步扩增连接的方法将口蹄疫病毒结构蛋白基因P1 2A、3C蛋白酶基因和 3D聚合酶基因按正确的读码框依次连接克隆入 pGEM T载体。然后 ,将切取的目的基因亚克隆入腺病毒穿梭质粒 pShuttle CMV。构建成功的 2个重组穿梭质粒经测序鉴定 ,含有完整的目的基因表达盒 ,穿梭质粒可与腺病毒骨架载体进行细菌内同源重组 。
Two recombinant adenoviral pShuttle-CMV plasmid containing FMDV type O capsid , 3C protease and 3D polymerase coding regions were constructed by the methods of multi-step cloning and ligating PCR. The recombinant pShuttle-CMV plasmids were confirmed by PCR,digestion of restricted endonuclease and sequencing.These recombinant pShuttle-CMV can be used to create recombinant adenovirus containing FMDV capsid and no-structural protein genes.
