宿主菌的选择
重组质粒的构建一般选择遗传稳定,转化效率高,质粒产量高的菌株作为受体菌,常用的有E.coli DH5α,E.coli JM 109,E.coli DH 10B,E.coli NovaBlμe等。作为表达宿主菌必须具备几个基本特点:遗传稳定,生长速度快,表达蛋白稳定。
具体操作过程中,根据所使用的表达载体的特点,目的基因密码子的组成等选择特定的表达宿主菌。以下是常用的几种表达宿主:BL2:lon和ompT蛋白酶缺陷型,避免了宿主对外源蛋白的降解。是经典的使用最广泛的表达受体。适用于Tac,Trc,Lac,λPL,cspA等作为启动子的载体。
BL21(DE3):DE3噬菌体溶源于BL21形成的带有染色体T7 RNA聚合酶基因大肠杆菌。IPTG诱导的lacΜV5启动子控制T7 RNA聚合酶基因表达T7 RNA聚合酶,进而控制T7表达系统表达目的蛋白。
