Used in biomedical research to quantify alanine transaminase levels in serum or plasma samples, this ELISA kit enables assessment of liver function and hepatocellular health. It is commonly applied in preclinical studies, toxicology evaluations, and clinical research to monitor liver injury caused by drugs, alcohol, or diseases such as hepatitis and fatty liver disease. The assay provides a sensitive and specific means to detect ALT concentration changes, supporting early diagnosis and mechanistic studies of liver damage. It is also utilized in pharmaceutical development to evaluate drug-induced liver toxicity in animal models or cell cultures.
