Galactose Assay Kit (Colorimetric/Fluorometric) (ab83382) provides a simple and convenient method for direct measurement of galactose levels in various biological samples such as serum, plasma and other body fluids, as well as food and growth media. In this assay, oxidation of galactose generates a product that reacts with the galactose probe to produce color (OD570nm) or fluorescence (Ex/Em 535/587 nm). Liquid samples can be tested directly without purification. The assay is fast, convenient and sensitive. It can also be used as a high throughput assay.
High concentrations of lactose could result in elevated readings for free galactose. Galactose oxidase is not completely selective, and it can react with the galactose moiety of lactose.

This product is manufactured by BioVision, an Abcam company and was previously called K621 Galactose Colorimetric/Fluorometric Assay Kit. K621-100 is the same size as the 100 test size of ab83382.
Galactose (C6H12O6 MW: 180.16 g/mol) is one of the major naturally occurring sugars, a monosaccharide that differs from glucose only by the configuration of the hydroxyl group at the carbon-4 position. Often present as an anomeric mixture of α-D-galactose and β-D-galactose, this monosaccharide exists abundantly in milk, dairy products and many other food types such as fruits and vegetables.
