Use
Ethidium bromide (EtBr) is a fluorescent dye widely used in molecular biology research. Early usage was as a veterinary trypanocide. It is a mutagenic compound that intercalates double-stranded DNA and RNA. The fluorescence of EtBr increases 21-fold upon binding to double-stranded RNA, 25-fold on binding double-stranded DNA (although histones block binding of EtBr to DNA). Ethidium bromide has been used in multiple 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 the binding to DNA, EtBr is a powerful inhibitor of DNA polymerase.
