IRE1-XBP1細(xì)胞應(yīng)激測定#U0921G:
使用明亮的IRE1-XBP1比率電池應(yīng)力傳感器在讀板器上檢測應(yīng)力響應(yīng)。CMV啟動(dòng)子。
該傳感器基于在內(nèi)質(zhì)網(wǎng)應(yīng)激期間由IRE1蛋白剪接的XBP1 mRNA。當(dāng)細(xì)胞經(jīng)受內(nèi)質(zhì)網(wǎng)(ER介導(dǎo)的)應(yīng)激或經(jīng)歷未折疊蛋白反應(yīng)(UPR)時(shí),紅色熒光蛋白組成性表達(dá),而傳感器產(chǎn)生非常亮的綠色熒光。只使用綠色熒光測量應(yīng)力,或者取綠色和紅色通道的比例。此外,紅色和綠色熒光蛋白都是核定位的,用于簡單的細(xì)胞分割和圖像分析。
艾美捷 Montana Molecular新型IRE1-XBP1 ER應(yīng)力測定試劑盒特點(diǎn):
1、通過UPR的IRE1-XBP1臂檢測細(xì)胞應(yīng)激
2、細(xì)胞在承受壓力時(shí)產(chǎn)生亮綠色熒光,并組成性表達(dá)紅色FP用于比率分析或監(jiān)測細(xì)胞健康
3、測量綠色熒光或取綠色/紅色熒光比,兩者都具有高Z’
4、綠色和紅色熒光以細(xì)胞核為目標(biāo),以簡化使用顯微鏡或高含量成像系統(tǒng)的圖像分析
5、這是#U0901G的更新,使用明亮、快速折疊的Montana Paintbrush RFP對(duì)讀板器進(jìn)行更強(qiáng)大的檢測
