Use
Kit for measurement of aspartate-aminotransferase in serum or plasma – Kinetic UV optimized method IFCC* * International Federation of Clinical Chemistry and Laboratory Medicine
Summary
AST measurements are used in the diagnosis and treatment of certain types of liver and heart disease.
Principle
The enzyme aspartate-aminotransferase (AST) (or glutamic-oxaloacetic transaminase/GOT) catalyzes reaction between alpha-ketoglutarate and L-aspartate giving glutamate and oxaloacetate. In presence of malate dehydrogenase (MDH), oxaloacetate reacts with NADH giving malate and NAD+. The rate of decrease of absorbance due to oxidation of NADH to NAD+ is directly proportional to sample AST activity.
