We offer Ethidium bromide in water as a safer alternative to the more hazardous solid form. Ethidium bromide is an intercalating reagent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology for techniques such as 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). It is commonly abbreviated as "EtBr". When exposed to ultraviolet light, it will fluoresce with an orange color, intensifying almost 20-fold after binding to DNA. Ethidium bromide has also been used extensively to reduce mitochondrial DNA copy number in proliferating cells.
