载体描述

pET42系列载体是用来进行克隆和高水平表达含有220个氨基酸的GST融合纯化标签的蛋白表达载体。

pET42a载体的单一的多克隆位点见上面的环状质粒图谱。注意:载体序列是以pBR322质粒的编码规矩进行编码的,所以T7蛋白表达区在质粒图谱上面是反向的。T7 RNA聚合酶启动的克隆和表达区域在质粒图谱中也被标注了出来。质粒的F1复制子是被定向的,所以在T7噬菌体聚合酶的作用下,包含有蛋白编码序列的病毒 粒子能够产生,并启动蛋白表达,同时蛋白表达将被T7终止子序列的作用下终止蛋白翻译。

转导生物公司pET42a载体,在BamHI和KpnI酶切位点间,用HRV 3C蛋白酶切位点代替Factor Xa,可以将融合表达的GST标签完全切除。

The recombinant human rhinovirus (HRV 3C) protease is used to remove fusion tags from proteins with the HRV 3C cleavage sequence (PreScission Site): Leu-Glu-Val-Leu-Phe-Gln↓Gly-Pro or LEVLFQ↓GP.

The recombinant HRV 3C protease is a fusion protein of 22-kDa size, with a his tag. The enzyme retains high activity at 4°C, and can cleave the target protein in solution, in dialysis or on column.
