A DNA stain used as a tracking dye in acid buffers for electrophoresis. Methyl Green was used as a topical antiseptic, however, it was withdrawn due to unwanted effects. The traditional Methyl Green has not manufactured for decades. The dye sold as Methyl Green is more accurately described as Ethyl Green. Both, Methyl Green and Ethyl Green are sold as double zinc salts.
