一般描述

细胞核是真核细胞中的一种包膜细胞器。核内含有细胞′的大部分遗传基因,以多条DNA线性长链形式与各种蛋白(如组蛋白)复合形成染色体。过去,细胞核的显微分析一直采用DAPI和Hoechst等DNA染料,但是这些染料需要固定细胞,不能对活细胞显色。

BioTracker 488绿色活细胞核染料是一种可穿过细胞膜的绿色荧光DNA染料,可特异性染色活细胞或固定细胞中的细胞核。染料具有优异的DNA特异性,无需洗涤操作,低毒性适合活细胞成像。本品同时提供1瓶维拉帕米,一种外排泵抑制剂,可促进某些细胞的探针保留和活细胞染色。

注意:BioTracker细胞核染料还会在DAPI通道发出蓝色荧光,可能不适合与蓝色探针一起进行多色成像。
