Description

Acridine Orange is a lysomotropic probe that can also be used for analysis of autophagy and to label DNA in living cells.

Acridine Orange is a cell-permeant dye that accumulates in acidic organelles in a pH-dependent manner and has been used for autophagy detection as well as for cell cycle determination. It can be used for cell-cycle studies because it emits with a green fluorescence (ex. max: 502 nm; em. max: 525 nm) when bound to dsDNA but with red fluorescence when bound to ssDNA or RNA (ex. max: 460 nm; em. max: 650 nm). The same red/green shift has also been used for lysosomal analysis in fluorescence microscopy and flow cytometric analysis since it emits green at neutral pH but with red fluorescence in acidic environments. It has also found use in cellular physiology studies and in the fluorescent microscopic examination of microorganisms. Acidotropic dyes like Acridine Orange will typically only stain late autophagic vacuoles.
