The fluorescence of EtBr increases 21-fold upon binding to double-stranded RNA and 25-fold on binding double-stranded DNA so that destaining the background is not necessary with a low stain concentration (10 µg/ml). 2010-12-16 · Introduced in the 1950s, ethidium bromide (EB) is still used as an anti-trypanosomal drug for African cattle although its mechanism of killing has been unclear and controversial. EB has long been known to cause loss of the mitochondrial genome, named kinetoplast DNA (kDNA), a giant network of interlocked minicircles and maxicircles. 18 Apr 2016 As both these LD50s are many orders of magnitude higher than the concentrations used in molecular biology, toxicity of gel staining solutions is  Ethidium Bromide (EtBr, CAS# 1234-45-8) is widely used in biochemical research laboratories for visualizing DNA fragments, and is primarily used on campus  Ethidium bromide (EtBr) is commonly used as a non-radioactive marker for identifying and visualizing nucleic acid bands in electrophoresis and in other  Ethidium bromide is a sensitive fluorescent stain for visualizing DNA in agarose and polyacrylamide gels. It is excited with a standard 302 nm UV transilluminator   25 Aug 2014 Ethidium Bromide or EtBr is an intercalating agent.

Molecules of the dye adhere to DNA strands and fluoresce under UV light, showing you exactly where the bands are within the gel. Ethidium 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 It is also not classified as a cancerogenic substance by the regulation bodies (for example see the National Toxicology Program of the US on Ethidium bromide).

Caution: Ethidium bromide is a toxic chemical and a mutagen. It causes eye and skin irritation. Ethidium bromide is an intercalating agent that is used as a fluorescent tag during electrophoresis. When you run a gel, the DNA will form bands which represent the size of the segments.

Ethidium has several experimentally useful properties including binding to nucleic acids, noncompetitive inhibition of nicotinic acetylcholine receptors, and fluorescence among others. It is most commonly used as the bromide.
