Amylase is found primarily in the pancreas and salivary glands. Elevated serum levels are associated with acute pancreatitis and other pancreatic disorders as well as mumps and bacterial parotitis.


This Amylase procedure utilizes 2-chloro-4-nitrophenyl-a-D-maltotrioside (CNPG3) as substrate.2 This substrate reacts directly with a-Amylase and does not require the presence of ancillary enzymes. The release of 2-chloro-4-nitrophenol (CNP) from the substrate and the resulting absorbance increase per minute is directly related to the a-Amylase activity in the sample. The resulting increase in absorbance can be measured spectrophotometrically at 410/480nm. (Package Insert: OSR General Chemistry BAOSR6x06.02; 2012-01)
