應用
溴化乙锭溶液已用于消耗mtDNA,以研究自噬中的线粒体损伤信号。它也已被用于通过彗星检测法(comet assay)检测DNA损伤。
溴化乙啶 (EtBr) 为聚丙烯酰胺凝胶电泳或琼脂糖凝胶电泳中最常用的核酸染料。EtBr 在结合到双链 RNA 上时其荧光可提高 21 倍,在结合到双链 DNA 上可提高 25 倍,从而使得在低染料浓度 (10μg/ml) 下无需背景脱色。溴化乙啶已用于核酸的许多荧光分析。已表明它可结合到单链 DNA(虽然强度不高)和三链 DNA 上。由于 EtBr 能够结合到 DNA 上,因此它是 DNA 聚合酶的抑制剂。
生化/生理作用
溴化乙啶可插入双链 DNA 和 RNA 中,并作为移码诱变剂。它还可与吖啶橙结合用于区分存活的、凋亡的和坏死的细胞。
重構
对于在电泳后进行凝胶染色,应先用水将储存液样品稀释到 0.5μg/ml,再将凝胶孵育 15-30 分钟。通常无需脱色,但是如果必须降低背景色,则可在水中脱色 15 分钟。然后可在紫外灯箱(254nm 波长)中检测 DNA 条带。也可将溴化乙啶加到凝胶和电泳缓冲液(终浓度 0.5μg/ml)中,并在电泳后立即显影。
