Lactose Assay Kit

Lactose (C12H22O11) is a disaccharide comprised of galactose and glucose which form a β1-4 glycosidic linkage. Lactose is the major sugar in milk, making up around 2–8 % of milk (by weight).

The kit is suitable for lactose activity determination in milk, food, beverages and other biological samples, as well as for studying the effects of drugs on lactose metabolism.

The Lactose Assay Kit uses a specific enzyme-coupled reaction in which lactose is cleaved and the resulting galactose forms a colored product. The color intensity at 570 nm or fluorescence intensity at λEx = 530 nm/λEm = 585 nm is directly proportional to the lactose concentration in the sample.
