质粒介绍

      pET44系列载体是设计用来克隆和高水平表达含有495个氨基酸的Nus标签的蛋白表达载体。与pET-43.1系列载体相比，pET44系列载体额外编码一个N端的His蛋白纯化标签。
      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。对pET44a载体的单链测序可以使用COLIDOWN primer.
把表达的基因插入到载体的笔蝉丑础滨或者厂尘补滨限制性内切酶位点时，可以通过贰碍蛋白酶或者罢丑谤辞尘产颈苍蛋白酶将融合表达的狈耻蝉标签完全切除。
