MonScript? RTIII Super Mix with dsDNase (Two-Step) 是一款高效便捷的高質(zhì)量一鏈cDNA合成預(yù)混液,使用該預(yù)混液15分鐘內(nèi)可獲得長達(dá)12 kb大小的cDNA,獲得的cDNA下游可用于qPCR和普通PCR。 通過試劑盒提取的RNA中往往存在著一定程度的基因組DNA污染,如果逆轉(zhuǎn)錄前不做去除處理,下游進(jìn)行qPCR反應(yīng)時(shí)基因組DNA與cDNA會同時(shí)進(jìn)行擴(kuò)增,尤其是引物設(shè)計(jì)在同一外顯子上時(shí)。MonScript? RTIII Super Mix with dsDNase (Two-Step)預(yù)混液采用了高效的dsDNase,該酶具有熱敏感性,可在高溫條件下快速不可逆地失活。與傳統(tǒng)使用DNase I去除基因組DNA污染的方法相比,dsDNase無需額外加入EDTA進(jìn)行失活,不僅節(jié)省實(shí)驗(yàn)時(shí)間,而且降低了對逆轉(zhuǎn)錄反應(yīng)的抑制。MonScript? RTIII Super Mix with dsDNase (Two-Step)預(yù)混液采用去基因組DNA污染與逆轉(zhuǎn)錄分開進(jìn)行的操作方法,有效保證cDNA的高產(chǎn)量與不同豐度基因的逆轉(zhuǎn)錄一致性,以及RNA水平的準(zhǔn)確定量。
