Used in biomedical research to measure levels of aspartate aminotransferase (AST), an enzyme found in liver, heart, muscle, and kidney tissues. The kit helps assess organ damage, particularly liver injury, by detecting AST concentration in serum or plasma samples. Commonly applied in studies related to hepatotoxicity, drug-induced liver injury, and metabolic disorders. Provides a sensitive and specific method for quantifying AST in experimental models involving rabbits, supporting preclinical research and veterinary diagnostics.
