Glutamic-Oxalacetic Transaminase from porcine heart is widely used in biochemical research and clinical diagnostics. It plays a critical role in enzymatic assays, particularly in measuring transaminase activity, which is essential for studying amino acid metabolism and liver function. In clinical settings, it helps diagnose liver diseases and monitor tissue damage, as elevated levels of this enzyme in blood serum indicate liver or heart cell injury. Additionally, it is utilized in laboratory experiments to understand metabolic pathways and enzyme kinetics, contributing to advancements in medical and biochemical sciences.
