Used in biomedical research to measure aspartate aminotransferase enzyme levels in rat samples, this ELISA kit helps assess liver and heart function in experimental models. It is commonly applied in toxicology studies to evaluate organ damage caused by drugs or chemicals. Researchers also use it in disease models such as hepatitis, myocardial infarction, and metabolic disorders to monitor enzyme release as a marker of cellular injury. The assay provides a sensitive and specific way to quantify AST levels in serum, plasma, or tissue homogenates, supporting data interpretation in preclinical studies.
