pyronin

pyronin
A fluorescent red basic xanthene dye, the chloride of tetramethyldiaminoxanthene, p. Y or p. G (C.I. 45005), or of tetraethyldiaminoxanthene, p. B (C.I. 45010). These dyes, especially p. Y, are used in combination with methyl green for differential staining of RNA (red) and DNA (green); difference in staining result is probably due to the higher degree of polymerization of DNA; p. Y is also used as a tracking dye for RNA in electrophoresis.
