Ethidium bromide stock solution 10 mg/mL in aqueous solution, Biotechnology Grade
Ethidium Bromide solution is a fluorescent stain for visualizing nucleic acids in solution or in electrophoresis gels. At a concentration of 0.5 µg/ml, ethidium bromide is useful in agarose or acrylamide ges for band detection. It is used to detect as little as 10 ng of nucleic acid. At high concentrations (0.5 - 1.0 µg/ml), it may be used to facilitate purification of DNA in cesium chloride gradient.
