使用说明

信裕质粒平台的各批次质粒菌株发货前均经过严格的多重验证，如存在质量问题，请在收到产品的三个月内通知我司。收到质粒后请短暂离心，加入20μl ddH2O溶解质粒，取2μl转化至对应感受态中，挑取单克隆重新提取质粒后使用。如需获取其他详细信息请登录我司官网查询。

质粒简介

pET41系列载体是设计用来克隆和高水平表达蛋白质的载体，载体融合表达一个含有220个氨基酸的GST标签蛋白纯化片段。pET41a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。
pET-41a载体上面含有一个EK蛋白酶切位点，当将目的基因使用载体上面的PshAI限制性内切酶位点插入进去时，可以通过EK蛋白酶将载体上的融合的所有氨基酸序列包括GST标签序列，全部切除掉。
