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).
Ethidium bromide is likely the most well-known dye used for visualizing DNA. This dye can be used in the gel mixture, in the electrophoresis buffer or to stain the gel after it is run. Molecules of the dye adhere to DNA strands and fluoresce under UV light, showing where the bands are within the gel. Ethidium bromide is a potential carcinogen, so it must be handled with care.
