Used in research settings to quantify glutamine transaminase (GT) levels in biological samples such as serum, plasma, or tissue homogenates. The kit enables detection of enzyme activity associated with amino acid metabolism, supporting studies in liver function, metabolic disorders, and oxidative stress. It is commonly applied in preclinical research and biomarker validation, providing a reliable method for measuring GT concentration through enzyme-linked immunosorbent assay (ELISA) with high sensitivity and specificity. Widely used in academic, pharmaceutical, and clinical laboratories for investigative purposes only, not for diagnostic use.
