          E2F-Luc螢光素酶報(bào)告基因(報(bào)告基因質(zhì)粒)(E2F luciferase reporter plasmid)是翌圣生物自主研發(fā)的用于檢測(cè)E2F轉(zhuǎn)錄活性水平為目的的報(bào)告基因。E2F轉(zhuǎn)錄因子在細(xì)胞周期調(diào)控中其重要的作用。研究證明,E2F-1對(duì)細(xì)胞的生長(zhǎng)具有雙向調(diào)節(jié)作用,可以調(diào)節(jié)細(xì)胞的增殖和凋亡。因此,E2F與腫瘤發(fā)生、細(xì)胞凋亡、腫瘤抑制等均有密切關(guān)系。

          E2F 報(bào)告基因主要用于檢測(cè)細(xì)胞中Cell Cycle信號(hào)通路、藥物研究、基因過(guò)表達(dá)和RNAi的表型分析等。

          pE2F-Luc是翌圣生物改造后的哺乳動(dòng)物真核表達(dá)載體,在其多克隆位點(diǎn)插入了多個(gè)E2F結(jié)合位點(diǎn),可以高靈敏度地檢測(cè)E2F的激活水平。同時(shí),對(duì)載體中預(yù)測(cè)出的其它轉(zhuǎn)錄因子以外的結(jié)合位點(diǎn)進(jìn)行了適當(dāng)?shù)耐蛔?,在保持原有功能不變的情況下,增加了質(zhì)粒的轉(zhuǎn)錄因子結(jié)合特異性。由于質(zhì)粒體積減小,使得E2F報(bào)告基因更易于轉(zhuǎn)染。
