Used in research settings to quantify levels of glutathione-S-transferase P1 (GSTP1) in human biological samples such as serum, plasma, or tissue homogenates. This assay is commonly applied in studies related to oxidative stress, cancer biomarker discovery, and drug metabolism. Elevated GSTP1 levels are associated with certain cancers, including prostate and liver cancers, making this kit valuable in investigating disease mechanisms and potential diagnostic markers. It is also used in toxicology research to assess cellular responses to environmental toxins and chemotherapeutic agents. The kit enables high-throughput, sensitive, and specific detection of GSTP1 protein, supporting both clinical research and pharmaceutical development.
