Biochem/physiol Actions
溴化乙啶可插入双链 DNA 和 RNA 中,并作为移码诱变剂。它还可用于区分存
活的、凋亡的和坏死的细胞。 包装
1, 5, 10, 25 g in glass btl
Reconstitution
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。 Application
Ethidium bromide is an aromatic cationic dye, is one of the most studied DNA-intercalating agents and has been used widely as a molecular probe. It is also used in the prophylaxis and treatment of animal trypanosomiasis in affected areas worldwide.†

文献和实验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
Ethidium Bromide Decontamination
N.B.: Ethidium bromide is a powerful mutagen. Protective gloves should be worn at all times when handling solutions containing ethidium bromide. Decontamination of solutions > 0.5mg/ml This method reduces the mutagenic activity
Caution: EtBr is a powerful mutagen and is moderately toxic. Wear gloves when working. When EtBr conc. is >0.5 mg/ml: 1.Add sufficient water to reduce the concentration of EtBr to 2.Add 1 volume of 0.5 M KMnO4. Mix, add 1 volume of 2.5 N HCl
