Glutathione S-Transferase (GST) Activity Assay Kit is widely used in biochemical and pharmaceutical research to measure the activity of GST enzymes. These enzymes play a crucial role in detoxification processes by catalyzing the conjugation of glutathione to various toxic compounds, making them more water-soluble and easier to excrete from the body. Researchers utilize this kit to study the effects of drugs, environmental toxins, and oxidative stress on GST activity, providing insights into cellular defense mechanisms. It is also employed in drug development to assess the efficacy of compounds designed to modulate GST activity, particularly in cancer research where GST overexpression is linked to drug resistance. Additionally, the kit is valuable in environmental studies to evaluate the impact of pollutants on organisms and ecosystems by measuring changes in GST activity as a biomarker of stress or toxicity.
