Acridine yellow, also known as acridine yellow G, acridine yellow H107, basic yellow K, and 3,6-diamino-2,7-dimethylacridine, is a yellow dye with strong bluish-violet fluorescence. It is a derivate of acridine. In histology, it is used as a fluorescent stain, and as a fluorescent probe for non-invasive measurements of cytoplasmic pH changes in whole cells. It is also used as a topical antiseptic. It is usually available as a hydrochloride salt. Acridine yellow damages DNA and is used as a mutagen in microbiology.
