Undegraded glycosaminoglycans form a complex with 1-ethyl-2-[3-(1-ethylnaphtho-[1,2-d]thiazolin-2-ylidene)-2- methylpropenyl]naphtho-[1,2-d]thiazolium bromide (Stains-all) in solution resulting in a characteristic shift in spectrum. Hyaluronic acid (a nonsulfated glycosaminoglycan) reacts with the dye to form a complex with an absorbance maximum at 650 nm, while
