简单介绍

pTrcHis2A大��pTrc系列表达质粒是为高效重组蛋白表达和大肠杆菌纯化而设计的pbr322表达载体。使用trp(trp - lac)启动子(Egon et al .，1983)和rrnB反终止区域(Li et al .，1984)可能会有较高的表达水平。trc启动子包含trp启动子的- 35区域和lac启动子的- 10区域(Brosius et al .，1985;大多et al .,1983;穆里根et al .,1985)。pTrcHis2A大肠pTrc系列表达质粒为了调节表达，在pTrcHis2载体中提供了编码Lac抑制因子(lacIq)的基因，允许对trc启动子进行调控，不管宿主菌株是否含有一个编码了Lac抑制因子的基因。

质粒简介

pTrcHis2A质粒是一个大肠杆菌蛋白表达载体，Trc启动子驱动目的基因的表达。The pTrcHis2 plasmids are pBR322-derived expression vectors designed for efficient recombinant protein expression and purification in E. coli. High levels of expression are possible using the trc (trp-lac) promoter (Egon et al., 1983) and the rrnB anti-termination region (Li et al., 1984). The trc promoter contains the –35 region of the trp promoter together with the –10 region of the lac promoter (Brosius et al., 1985; Egon et al., 1983; Mulligan et al., 1985). To regulate expression, the gene encoding Lac repressor (lacIq) is provided in the pTrcHis2 vectors, allowing regulation of the trc promoter regardless of whether the host strain contains a gene encoding the Lac repressor. Isopropyl-Beta-D-thiogalactopyranoside (IPTG) is used to induce expression of your gene. Translation is enhanced by the bacteriophage T7 gene 10 translation enhancer and a minicistron that provides highly efficient translational restart into the open reading frame of the multiple cloning site. DNA inserts are positioned downstream and in frame with the initiation ATG and a C-terminal fusion peptide. The C-terminal peptide encodes the myc epitope and six histidine residues that function as a metal binding site in the expressed protein.
