简单介绍

pETBlue-2大肠pET系列表达��粒2向量的目的是确定重组传统蓝色/白色筛选目标基因的表达,同时允许T7lac推销商。pETBlue-2大肠pET系列表达质粒筛选是独立于表达的，因为T7lac表达启动子相对于介导蓝/白筛选的大肠杆菌启动子处于相反的方向。petblue - 2定义了打开的阅读框架，如果需要表达，插入必须被复制到帧中。

质粒简介

pETBlue-2是一个大肠杆菌pET系列表达质粒。The pETBlue™-2 vector is designed to identify recombinants by traditional blue/white screening while also allowing T7lac promoter based expression of target genes. Screening is independent of expression because the T7lac expression promoter is in an opposed orientation relative to the E. coli promoter that mediates blue/white screening. pETBlue-2 defines the open reading frame and inserts must be cloned in-frame if expression is desired. The vector features an expanded multiple cloning site (MCS) and optional C-terminal HSV•Tag® and His•Tag® sequences. The sequence is numbered from the first base of the T7 promoter sequence.
