Used in biomedical research to quantify levels of gamma-glutamyl transferase 1 (GGT1) in human biological samples such as serum, plasma, or tissue extracts. This ELISA kit enables researchers to study GGT1 expression in liver diseases, including hepatitis, cirrhosis, and fatty liver disease, where elevated GGT levels are common. It is also applied in drug development and toxicology studies to assess hepatotoxicity caused by pharmaceuticals or environmental agents. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for clinical research settings investigating oxidative stress, glutathione metabolism, and cellular damage. Additionally, it aids in monitoring disease progression and response to treatment in metabolic and alcohol-related disorders.
