Galactose and Lactose Assay Kit (Colorimetric/Fluorometric) (CAT#: CB-P188-K) Datasheet

Product Type
Creative Biolabs' galactose and lactose content assay kits provide a simple for directly measuring the galactose and lactose content in various biological samples (serum, plasma, other body fluids, food, growth medium, etc.). In order to detect galactose, galactose oxidase specifically oxidizes free galactose to produce a product that reacts with the galactose probe to produce color (OD570nm) and Fluorometric (Ex / Em 535/587). To detect lactose, lactose is hydrolyzed by lactase to produce free galactose, which is then measured. Therefore, lactose level = total galactose-free galactose.
