Acridine orange
Acridine Orange base (3,6-Bis(dimethylamino)acridine) is a cell-permeable fluorescent dye that binds to nucleic acids. It emits green fluorescence when bound to dsDNA and red fluorescence when bound to ssDNA or RNA. It is also known to be a positive solvatochromic dye. Acridine orange has also been used as a lysosomal dye. It is widely used to detect the presence of homeopathic potencies.
