1.3.2雙熒光素酶報告基因?qū)嶒?yàn)

參照前期的實(shí)驗(yàn)方法:將HEK293T細(xì)胞(人胚腎細(xì)胞)培養(yǎng)于含10%胎牛血清的DMEM培養(yǎng)基中,并放置于37℃,含5%CO2的細(xì)胞培養(yǎng)箱內(nèi)。細(xì)胞接種于24孔板中24h后,用Lipofectamine2000轉(zhuǎn)染pNF-κB-luc和pRL-TK質(zhì)粒后繼續(xù)培養(yǎng)18h,加入不同濃度的待測化合物孵育4h后加入10ng/mLTNF-α再繼續(xù)培養(yǎng)4h。之后按照雙熒光素酶報告基因檢測試劑盒說明書檢測化合物1~19對NF-κB信號通路活性的影響。
