Se hela listan på Ethidium bromide is the most commonly used dye for DNA and RNA detection in gels. Ethidium bromide is a DNA intercalator, inserting itself between the base pairs in the double helix. Ethidium bromide has UV absorbance maxima at 300 and 360 nm, and an emission maximum at 590 nm. Ethidium bromide is a molecule commonly used to visualize DNA in agarose gel electrophoresis experiments.
