Product Description

Ethidium Bromide Solution

Application Notes

Ethidium bromide(EtBr) has been used extensively to reduce mitochondrial DNA copy number in proliferating cells and most commonly used in 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.4 Because of its ability to bind to DNA, EtBr is an inhibitor of DNA polymerase.
