Acridine orange hydrochloride is a cell and organelle membrane permeable fluorescent dye that targets nucleic acids. Acridine orange can either be incorporated into double helical nucleic acids (detected by green fluorescence at 530 nm), or bind electrostatically to phosphate groups of single-stranded molecules (detected by red fluorescence at 640 nm), which renders it the ability to differently stain DNA and RNA or single-stranded DNA in situ. For unfixed cells, acridine orange staining can still be used as a simple, fast approach of obtaining information on cell cycle status and cell ploidy levels from DNA staining (green fluorescence), as well as cell transcriptional activity from RNA measurements (red fluorescence), in a flow cytofluorometric system. Thus, acridine orange may serve as a useful cytochemical stain for cell-cycle and apoptosis studies.
