Galactose oxidase (GAO) produced by the fungus Dactylium dendroides is used in the quantitative determination of galactose in blood and other biological fluids. Because GAO oxidizes galactose even in polysaccharides it has been used to locate galactose histochemically and to detect and distinguish glycoproteins.
