• Beschreibung: Applications Ethidium bromide (EtBr) is the most commonly used nucleic acid stain for PAGE or agarose gel electrophoresis. 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). Ethidium bromide has been used in a number of fluorimetric assays for nucleic acids. It has been shown to bind to single-stranded DNA (although not as strongly) and triple-stranded DNA. Because of its ability to bind to DNA, EtBr is an inhibitor of DNA polymerase. Antiprotozoal (Trypanosoma). Dyes and metabolites. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the packageReferences Waring, M.J., et al.: J. Mol. Biol., 13, 269 (1965), Probst, G.S., et al.: Environ.
