α-AMYLASE (EC 3.2.1.1) belongs to the family of glycoside hydrolase enzymes that break down starch into glucose molecules by acting on α-1,4-glycosidic bonds. The α-amylases cleave at random locations on the starch chain, ultimately yielding maltotriose and maltose, as well as glucose and 'limit dextrin' from amylose and amylopectin. In mammals, α-amylase is a major digestive enzyme. Increased α-amylase levels in humans are associated with salivary trauma, mumps due to inflammation of the salivary glands, pancreatitis and renal failure.
Simple, direct and automation-ready procedures for measuring amylase activity are very desirable. BioAssay Systems’ QuantiChrom™ α-Amylase Assay Kit provides a convenient colorimetric method to measure α-amylase activity in biological samples. In this assay, α-amylase hydrolyzes a synthetic substrate to release 2-chloro-4-nitrophenol. The rate of formation of the 2-chloro-4-nitrophenol, measured at 405 nm, is directly proportional to the enzyme activity.
