Ethidiumbromide
Introduction Ethidium bromide (EtBr), 3,8-diamino-5-ethyl-6-phenylphenanthridinium bromide, is commonly used as a non-radioactive marker for identifying and visualizing nucleic acid bands in electrophoresis and other methods of gel-based nucleic acid separation. EtBr is a dark red crystalline that readily fluoresces reddish-brown when exposed to ultraviolet (UV) light. EtBr is a potent mutagen and toxic af......阅读全文
4′,6二脒基2苯基吲哚的染色剂的染色原理
可用于细胞核染色的试剂是一种可以穿透细胞膜的蓝色荧光染料。和双链DNA结合后可以产生比DAPI自身强20多倍的荧光。和EB（ethidium bromide）相比，对双链DNA的染色灵敏度要高很多倍。DAPI染色常用于细胞凋亡检测，染色后用荧光显微镜观察或流式细胞仪检测。DAPI也常用于普通的细胞核
