WebSep 13, 2024 · Acridine orange is a cell-permeable, nucleic acid selective fluorescent dye that emits green fluorescence when bound to dsDNA (at 520 ) and red fluorescence when bound to ssDNA or RNA (at 650 nm). Since it is a cationic dye, it also enters acidic compartments such as lysosomes which, in low pH conditions, will emit orange light.
