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).
As a result, many organobromide compoundsâsuch as the pesticide methyl bromideâare no longer used. Bromine compounds are still used in well drilling fluids, in photographic film, and as an intermediate in the manufacture of organic chemicals. Although large amounts are toxic and cause bromism, a clear biological role for bromide and hypobromous acid has recently been elucidated, and it now appears that bromine is an essential trace element.
