Cat No.
NATE-0273
Description
Galactose oxidase is an extracellular copper-containing enzyme, secreted by the deuteromycete fungus Dactylium dendroides. It catalyzes the oxidation of a range of primary alcohols, including D-galactose, to the corresponding aldehyde, with reduction of oxygen to hydrogen peroxide.
Abbr
Galactose Oxidase, Native (Dactylium dendroides)
Species

9028-79-9
Unit Definition
One unit will produce a ΔA425 of 1.0 per min at pH 6.0 at 25°C, in a peroxidase and o-tolidine system. Reaction volume = 3.4 mL. Light path = 1 cm.
Applications
Galactose oxidase may be used as an analytical tool for the specific determination of D-galactose in blood plasma, plant extracts, and phospholipids. It could be used for the characterization of terminal D-galactoside units in several polymers. It may also be useful in the determination of lactose.
Warnings
Chromatographically purified
