Beskrivelse: Acridine orange is a metachromatic dye which can stain DNA, RNA and acid glycosaminoglycans. At low concentrations, it intercalates into DNA and precipitates RNA. However, at high concentrations it denatures and precipitates both RNA and DNA. Acridine orange is also used to analyse autophagy. It enters into acidic organelles in a pH-dependent manner. At neutral pH, acridine orange gives a green fluorescence and in acidic conditions, it accumulates in acidic organelles giving a bright red fluorescence.
