產(chǎn)品描述
GAS-GFP報告基因是自主研發(fā)的用于檢測STAT1/STAT1轉(zhuǎn)錄活性水平為目的的報告基因。GAS(gamma-activated sequence, GAS) 又稱γ干擾素活化序列在皮膚發(fā)生遲發(fā)型接觸性過敏時，可與轉(zhuǎn)位至角朊細(xì)胞核內(nèi)的STAT-91結(jié)合而激活K17的表達(dá)。
GAS-GFP報告基因主要用于檢測細(xì)胞中干擾素調(diào)控的信號通路的活性、**研究以及基因過表達(dá)和RNAi的表型分析等。
pGMGAS-GFP是改造后的哺乳動物真核表達(dá)載體，在其多克隆位點插入了多個STAT1/STAT1結(jié)合位點，可以高效地檢測STAT1/STAT1的激活水平。由于載體采用了GFP作為報告基因，更便于后續(xù)的檢測。同時，對載體中預(yù)測出的其它轉(zhuǎn)錄因子以外的結(jié)合位點進行了適當(dāng)?shù)耐蛔?，增加了質(zhì)粒的轉(zhuǎn)錄因子結(jié)合特異性。另外，由于質(zhì)粒體積減小，使得GAS-GFP報告基因更易于轉(zhuǎn)染。GAS GFP Reporter Plasmid（GAS-GFP報告基因質(zhì)粒）
