质粒简介

pET-30a质粒是一种原核表达载体，C端含有一个6×His affinity标签，N端含有一个thrombin位点、6×His affinity标签、EK标签和S标签。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。
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。

The pET-30a-c(+) vectors carry an N-terminal His• Tag®/ thrombin/ S• Tag™/ enterokinase configuration plus an optional C-terminal His• Tag sequence. Unique sites are shown on the circle map. Note that the sequence is numbered by the pBR322 convention, so the T7 expression region is reversed on the circular map. The cloning/expression region of the coding strand transcribed by T7 RNA polymerase is shown below. The f1 origin is oriented so that infection with helper phage will produce virions containing single-stranded DNA that corresponds to the coding strand. Therefore, single-stranded sequencing should be performed using the T7 terminator primer .
