Description: 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.

Description: Phenolphthalein is an acid base indicator. It is a weak acid, which is colorless in acidic solution and turns puce pink in alkaline solution. Phenolphthalein is genotoxic. It might cause oxidative damage and binds to estrogen receptors. Phenolphthalein solution is a synthetic indicator. It is colorless in acidic and neutral conditions. Phenolphthalein gives pink color when added to a base, therefore it is considered as a base indicator.
