Used in biomedical research to quantify levels of human alpha glutathione S-transferase (α-GST) in biological samples such as serum, plasma, and tissue homogenates. It is particularly valuable in studies related to cellular stress, liver injury, and apoptosis, as α-GST is released into the bloodstream following hepatocyte damage. The ELISA kit enables high sensitivity and specificity in detecting α-GST, making it a reliable tool for assessing organ damage, especially in drug development and toxicology studies. It is also employed in cancer research, where altered expression of GST isoenzymes may indicate tumor resistance to chemotherapy. The assay supports high-throughput screening and is widely used in clinical and preclinical laboratories for biomarker validation.
