Glutamic-Pyruvic Transaminase from porcine heart, in its lyophilized powder form, is widely used in biochemical research and diagnostic applications. It plays a critical role in amino acid metabolism studies, particularly in understanding the transamination process where it catalyzes the transfer of amino groups between glutamate and pyruvate. This enzyme is essential in clinical diagnostics for measuring alanine aminotransferase (ALT) levels in blood samples, which is a key marker for liver function and liver disease detection. Additionally, it is utilized in enzyme assays and metabolic pathway analysis to study cellular processes and enzymatic activities. Its stability in lyophilized form makes it convenient for storage and use in laboratory settings.
