◆DAPI和Hoechst 染料非常相似,该如何选用?DAPI是一种非常普通的蓝色核复染荧光染料,能对固定和通透的细胞和组织的细胞核进行非常明亮的标记。遗憾的是,人们普遍认为它是介于半通透性到非通透性之间的染色剂,对活细胞的染色效果也不一致。Hoechst 33342染料是细胞通透性染料,与DAPI染色有相似的染色结合机制和荧光颜色;它是活细胞成像的首选,且对固定细胞的标记效果和DAPI一样好。◆DAPI染色的工作液浓度一般为多少,要怎么稀释?该试剂用于细胞染色时,需要根据具体的实验目的确定工作液浓度,常用的浓度0.5-10μg/ml,直接用水稀释即可。◆在细胞膜和细胞核双染实验中,细胞膜染色用DiI,细胞核染色用DAPI,细胞固定后,先染色DiI还是先染色DAPI?先用DiI对细胞膜进行染色,后用DAPI染核。◆DAPI和Hoechst可以用来示踪细胞吗?不可以,这些染料与DNA和RNA的结合会影响核酸的正常功能,扰乱转录和增殖。◆DAPI能否用来染色植物细胞的原生质体?可以,有文献报道使用DAPI染色原生质体,但是原生质体比较脆弱,DAPI对原生质体的杀伤力可能比较大。◆该试剂可对酵母菌进行荧光标记吗?有文献用DAPI染酵母样品,但我们目前没有相关经验,建议查看相关文献资料进行参考。◆该试剂可以染活细胞吗?DAPI染色时,细胞均需要固定操作,对于活细胞的染色效果较差。◆请问可以用于石蜡切片的免疫组化,进行染核吗?可以的。
