Used in research settings to quantify levels of Glutathione S-Transferase Mu1 (GSTM1) in human biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables scientists to study GSTM1 expression in relation to oxidative stress, detoxification processes, and susceptibility to diseases including cancer, respiratory conditions, and neurodegenerative disorders. It is particularly valuable in biomarker studies and environmental toxin research where GSTM1 activity may influence individual responses to pollutants or therapeutic agents. The assay provides a sensitive and specific means to measure protein concentration, supporting investigations in molecular epidemiology, pharmacogenetics, and cellular defense mechanisms.
