Description
Pyronin Y is an intercalating cationic dye that shows specificity towards RNA.
Pyronin Y is an organic chloride salt having 6-(dimethylamino)-N,N-dimethyl-3H-xanthen-3-iminium as the cation. Used with methyl green to selectively demonstrate RNA (red) in contrast to DNA (green) with the Unna-Pappenheim method. It has a role as a histological dye. It is an iminium salt and an organic chloride salt. It contains a pyronin Y cation.|Xanthene dye used as a bacterial and biological stain. Synonyms: Pyronin; Pyronine G; Pyronine Y. Use also for Pyronine B. which is diethyl-rather than dimethylamino-.
