Used in research settings to quantify levels of Glutathione S-Transferase pi (GSTpi) protein in rat tissue samples or biological fluids. This assay is particularly valuable in studies related to oxidative stress, detoxification processes, and cellular protection mechanisms in the liver, brain, and other organs. Commonly applied in toxicology research to assess the impact of environmental toxins, drugs, or heavy metals on cellular defense systems. Also utilized in cancer research, as GSTpi expression is often elevated in tumor cells and linked to drug resistance. The kit enables high-throughput, accurate measurement, supporting biomarker discovery and evaluation of therapeutic interventions in rodent models.
