Used in biomedical research to quantify glutamate pyruvate transaminase (GPT), also known as alanine aminotransferase (ALT), in human serum, plasma, or cell culture samples. This ELISA kit enables accurate measurement of GPT levels, which is critical for assessing liver function and detecting liver damage, such as in hepatitis, cirrhosis, or drug-induced liver injury. Widely applied in clinical laboratories and pharmaceutical research for biomarker validation, toxicity studies, and monitoring disease progression. The assay is sensitive, specific, and suitable for high-throughput analysis, supporting both diagnostic development and therapeutic evaluation.
