The Glutathione S-Transferase (GST) Activity Assay Kit is widely used to measure the activity of GST enzymes in various biological samples. This kit is essential in toxicology studies, as GST enzymes play a critical role in detoxification processes by conjugating glutathione to harmful compounds, facilitating their elimination from the body. It is also employed in cancer research to assess the role of GST in drug resistance, as elevated GST levels can reduce the effectiveness of certain chemotherapy agents. Additionally, the kit is utilized in environmental studies to evaluate the impact of pollutants on cellular detoxification mechanisms. In drug development, it helps screen compounds that modulate GST activity, aiding in the discovery of new therapeutic agents. The assay is also applied in basic biochemical research to study enzyme kinetics and the regulation of GST expression under different physiological conditions. Its simplicity and reliability make it a valuable tool across multiple scientific disciplines.
