Product Introduction
Ethidium bromide is an intercalating reagent that is used for double-stranded DNA and RNA in 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 ug/ml). Ethidium bromide acts as an inhibitor of DNA polymerase.
