质粒介绍

pET-25b质粒是一种原核表达载体，C端含有一个6×His标签、HSV标签，N端含有一个pelB前导肽。该质粒含有多个常用的酶切位点，便于不同基因克隆。表达由宿主细胞提供的T7 RNA聚合酶诱导，目的基因被克隆到质粒载体上，受噬菌体强转录及翻译信号控制。辫贰罢25产载体的单一的多克隆位点见上面的环状质粒图谱。注意：载体序列是以辫叠搁322质粒的编码规矩进行编码的，所以罢7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。
pET系统是有史以来在大肠杆菌中表达重组蛋白的功能*强大的系统，也是现今原核表达方面使用*广泛的系统。该系列质粒能很容易的通过降低诱导物的浓度来削弱蛋白表达。在非诱导条件下，可以使目的基因处于完全沉默状态而不转录。
