Alpha-Amylase Assay Kit (BA0082)
DescriptionAssay Genie's alpha-amylase assay method involves two steps: (1). alpha-amylase in the sample hydrolyzes starch and the product is rapidly converted to glucose by alpha-glucosidase and hydrogen peroxide by glucose oxidase; (2). hydrogen peroxide concentration is determined with a colorimetric reagent.
ApplicationsFor quantitative determination of alpha-amylase activity
- Sensitive and accurate. Linear detection range 0.3 to 50 U/L alpha-amylase in 96-well plate assay.
- Convenient. The procedure involves adding a single working reagent, incubation for 15 min, followed by the detection reagent and a 20-min incubation and reading the optical density at 585 nm.

More DetailsAMYLASE belongs to the family of glycoside hydrolase enzymes that break down starch into glucose molecules by acting on alpha-1,4-glycosidic bonds. The alpha-amylases (EC 18.104.22.168) cleave at random locations on the starch chain, ultimately yielding maltotriose and maltose, glucose and "limit dextrin" from amylose and amylopectin. In mammals, alpha-amylase is a major digestive enzyme. Increased enzyme 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.
