Ethidium bromide is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis. It is commonly abbreviated as EtBr which is also an abbreviation for bromoethane. When exposed to ultraviolet light it will fluoresce with an orange colour intensifying almost 20-fold after binding to DNA.
