Cas9核酸酶是一種向導RNA(guideRNA,gRNA)引導的核酸內切酶,可催化雙鏈DNA的裂解。NLS-Cas9-EGFP在Cas9核酸酶的基礎上進行改造,它在N端包含一個核定位信號(NLS),在C端包含一個EGFP和一個6X(His)序列。當Cas9以NLS序列表達時,Cas9RNP復合物在進入細胞后立即定位到細胞核。不需要體內轉錄或翻譯,提高了效率。此外,與其他系統(tǒng)相比,EGFP標簽可作為追蹤或分類轉染細胞的報告器,通過熒光細胞分選(FACS)富集所需基因組編輯的細胞群。它降低了在基因組編輯應用中與單細胞克隆和基因分型相關的人工和成本。產品特點如下:無DNA:沒有外部DNA添加;高切割效率:NLS確保Cas9蛋白高效進入細胞核;低脫靶效應:Cas9核酸酶的瞬時表達提高了切割的特異性;節(jié)省時間:無需轉錄和翻譯;減少勞動力:通過基于EGFP的FACS富集細胞群以進行所需的基因組編輯。C端His標簽增加了融合蛋白檢測方法的選擇。可應用于:通過體外DNA切割篩選高效和特異性靶向gRNA。通過電穿孔或注射與特定gRNA結合時的體內基因編輯。通過基于EGFP的FACS富集細胞群以進行所需的基因組編輯。儲存條件-25~-15℃保存,有效期1年。Recombinant Rhesus macaque DLL3 Protein,His Tag
