Invitrogen™ Aspartate Aminotransferase (AST/GOT) Activity Kit

The Aspartate Aminotransferase (AST/GOT) Assay Kit is a highly reliable and sensitive assay designed for the quantitative measurement of aspartate aminotransferase activity in various sample types. AST/GOT is a key enzyme in nitrogen metabolism, which is widely found in plasma and body tissues, including liver, heart, skeletal muscle, kidney, brain, pancreas, lung, and erythrocytes. Changes in AST/GOT activity were found in acute pancreatitis, ischemic stroke, severe burns, periodontitis, acute renal disease, and motor neuron disease.

The assay is based on the ability of AST/GOT to enable alpha-ketoglutaric acid and aspartic acid to displace amino and keto groups to form glutamic acid and oxaloacetic acid. Oxaloacetic acid can decarboxylate itself to form pyroracemic acid during the reaction. Pyroracemic acid reacts with 2,4-dinitro phenyl hydrazine (DNPH) to form 2,4, dinitrophenylhydrazone, showing reddish-brown color in alkaline solution. The OD values can be measured to calculate the enzyme activity.
