基本信息

質(zhì)粒圖譜和多克隆位點(diǎn)信息

注意：

客戶在我公司選擇構(gòu)建載體服務(wù)項(xiàng)目時(shí)，請(qǐng)自行提供母源載體。

如要使用本公司保存的母源載體時(shí)，本公司不能保證所有母源載體完全符合客戶預(yù)期，也不承擔(dān)由此產(chǎn)生的任何責(zé)任。

載體描述

pGEX-4T-1-6*His與pGEX-4T-1一樣，是一種常用的原核表達(dá)載體，具有Amp抗性，質(zhì)粒大小為4.9 kb。該載體多克隆位點(diǎn)區(qū)域含有多個(gè)常用的內(nèi)切酶位點(diǎn)序列，便于不同基因的克隆；且全序列中含有tac啟動(dòng)子、GST標(biāo)簽序列，是一種高效的蛋白表達(dá)載體。Tac啟動(dòng)子在沒(méi)有誘導(dǎo)物存在的情況下，質(zhì)粒上攜帶的lacIq基因產(chǎn)物可以有效抑制tac啟動(dòng)子的轉(zhuǎn)錄?？稍贐L21、Rosstea等表達(dá)菌株中高表達(dá)融合有GST標(biāo)簽的蛋白，且用凝血酶可將目的蛋白的GST標(biāo)簽切掉，同時(shí)C端帶有His標(biāo)簽，便于下游蛋白純化。
