Visualization: ethidium bromide (EtBr) and dyes The most common dye used to make DNA or RNA bands visible for agarose gel electrophoresis is ethidium bromide, usually abbreviated as EtBr. It fluoresces under UV light when intercalated into DNA (or RNA).
While the agarose is cooling, prepare the gel tank ready, on a level surface. Add 1 ÂµL of ethidium bromide (10 mg/mL) and swirl to mix. The reason for allowing the agarose to cool a little before this step is to minimise production of ethidium bromide vapour. Ethidium Bromide is mutagenic and should be handled with extreme caution
