pTeton載體質粒圖譜和多克隆位點信息
pTeton載體簡介
載體描述：
pTet-On表達反向抑制轉錄激活因子(reverse tet-responsive transcriptional activator, rtTA),該因子來自于巨細胞病毒立即早期啟動子（immediate early promoter of cytomegalovirus, Pcmv）.tTA是一段融合的1-207個氨基酸序列的Tet抑制子（TetR）和來自于單純皰疹病毒（Herpes simplex virus,HSV）的VP16蛋白帶負電荷C端激活域。
pTet-On與pTet-Off載體質粒相似，除了4個氨基酸的不同。這4個氨基酸的差異使得TetR轉變為rTetR，從而使得tTA轉變為rtTA. pTet-Off還包含有幾個沉默突變。
pTet-on載體被Gossen等（1995）原本描述為pUHD17-1neo.可以通過HindIII限制性內切酶酶切，來區分pTet-On和pTet-Off載體。
載體使用：
pTet-On載體被用來構建穩表達Tet-On細胞系。在將基因插入到載體的Tet抑制子元件（Tet-responsive element, TRE）控制下后，質粒可以用于轉染Tet-On細胞系，rtTA可以結合TRE，從而在多西環素（DOX）的存在條件下激活基因轉錄。DOX從培養基中去除后，TRE調控下的基因轉錄能夠在劑量依賴的條件下下調或者關閉。更多的關于TRE原件包含載體及Tet-On細胞系的操作構建步驟可以參見Tet 系統使用手冊（PT3001-1）。
