Used for the quantitative measurement of alpha-glutathione S-transferase (α-GST) activity in biological samples such as serum, plasma, and tissue homogenates from rats. This ELISA kit is particularly useful in toxicology studies to assess hepatotoxicity, as α-GST is a sensitive biomarker released into the bloodstream upon liver cell damage. It enables researchers to monitor liver injury in preclinical studies, evaluate drug-induced toxicity, and support the development of safer pharmaceuticals. The assay provides a reliable, high-throughput method for detecting early signs of cellular damage in rat models, making it valuable in both academic research and drug development.
