Methyl green is a synthetic, triphenylmethane-type cationic dye related to ethyl green mainly used as DNA stain in histochemistry. It possesses aniline rings with different degrees of methylation. The dye binds specifically to the A-T rich regions of the major groove of DNA with the help of two positive charges. Methyl green in combination with pyronin is extensively used to stain RNA and plasma cells in tissue sections and cytologic preparations.
