质粒简介

      pET50b载体携带有N端的Nus标签和His纯化标签，紧跟着这些标签的有一个HRV3C蛋白酶切位点。这个HRV3C蛋白酶切位点能够特异性的高效切割 “LEVLFQ↓GP”氨基酸序列，酶活力在低温下很强。pET-50b(+)载体上还含有一个可选择的C端Thrombin蛋白酶切位点和S标签序列。
      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。
