pTrcHis A質粒 pTrcHisA載體簡介
pTrcHis載體是來由pBR322質粒衍生而來的表達載體,設計用來在大腸桿菌中進行重組蛋白的高效表達和純化。
載體上的Trc啟動子和rrnB抗終止區使得高水平蛋白表達成為可能.Trc啟動子由Trp啟動子的-35區域和Lac啟動子的-10區域共同組成。pTrcHis載體同時包含有一個LacIq基因，該基因編碼了Lac啟動子的抑制蛋白。LacIq基因的存在使得宿主菌是LacIq+還是LacIq-都可以高效抑制插入基因的轉錄。
進行蛋白表達時，大腸桿菌需要生長到對數生長期，然后加入1mM IPTG，去除阻遏蛋白，誘導表達。載體上的迷你順反子結構能夠增強插入基因的轉錄水平，從而高水平表達目的蛋白。DNA插入片段位于載體表達片段下游，在其上游有一個N-端融合表達多肽序列，該序列包含有ATG起始密碼子，6xHis標簽，T7噬菌體10號基因的翻譯增強子，X press抗原表位，腸激酶酶切識別位點。
