Galactose (C₆H₁₂O₆, Gal) is a monosaccharide sugar and is a naturally occurring sugar that involved in many biological processes. Galactose combines with glucose to form lactose that is mainly present in milk and milk products.

The Galactose Colorimetric/Fluorometric Assay Kit provides a sensitive, fast and convenient way for detection of galactose levels in various biological samples (plasma, serum, growth media, other body fluids, food, etc.) based on colorimetric and fluorometric method. In the assay, galactose is specifically oxidized producing a product that yields fluorescence (Ex/Em 535/587 nm) and color (λmax = 570 nm). Liquid samples can be tested directly without purification. The kit is also suited for a high throughput assay.
