Application

A rigorously purified zinc-free material suitable for use in flow cytometry.
Acridine Orange hydrochloride hydrate dye has been used:
  • to stain intracellular acidic vesicles.
  • to measure lysosomal membrane permeability (LMP).
  • or autophagy detection.
Fluorescent stain for nucleic acids in agarose and polyacrylamide gels. Has been used to study apoptosis in various cell culture and tissue models.

Biochem/physiol Actions

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 analyze 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.
