Ethidium-D5 Bromide

Controlled Product

CAS: 1579939-34-6

Applications Labelled Ethidium bromide (EtBr) (E890700). It 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).
Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package
