. like sliding a card into a deck," which happens through a process known as intercalation. Ethidium bromide is a valuable aid for visualizing DNA in gels, but it is considered a “powerful mutagen with moderate toxicity” (MacGregor and Johnson, 1977). The greatest safety concern is during the preparation of a stock from the powdered ethidium bromide. CAUTION: Use great care when weighing out powdered ethidium bromide. 2020-01-09 2016-04-18 So we use Ethidium bromide to stain our agarose gels for dna extraction and analysis. The software in our gel doc is malfunctioning so we are unable to capture images.

Ethidium bromide is a potent mutagen, often used in laboratories to stain nucleic acids in electrophoresis gels. Ethidium bromide is not a regulated hazardous material, but due to its potential health hazards, precautions should be taken during handling and disposal. Ethidium Bromide (EtBr) is sometimes added to running buffer during the separation of DNA fragments by agarose gel electrophoresis. It is used because upon binding of the molecule to the DNA and illumination with a UV light source, the DNA banding pattern can be visualized. Click to see full answer Ethidium bromide (also known as homidium bromide) is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as EtBr, which is also an abbreviation for bromoethane. Ethidium bromide (EtBr) is a fluorescent dye widely used in molecular biology research.
