Ethidium Bromide Risks and Safe Handling: What You Need to Know
Year: 2024
Type: article
Abstract: Ethidium bromide, a household name in biology, is a fluorescent stain used to visualize nucleic acids in electrophoresis. It binds to DNA and fluoresces with a reddish-brown colour under ultraviolet light, intensifying its glow almost 20-fold. Discovered in the early 20th century, ethidium bromide's precursor, phenanthridine, was noted for its medicinal potential due to its quinoline ring structure. In 1938, phenanthridine derivatives effectively targeted Trypanosoma parasites causing African animal trypanosomiasis. By 1952, chemical modifications led to the development of ethidium bromide, a more potent and less toxic trypanocidal drug. Manufactured as Ethidium® by Boots Pure Drug Co., Ltd., it remained the preferred treatment for cattle trypanosomiasis for decades. Interestingly, its ability to intercalate DNA base pairs made it invaluable in molecular research, a discovery credited to Piet Borst and Cees Aaij. Today, it remains a staple in molecular biology laboratories worldwide.
