The Glutathione S-Transferase (GST) Activity Assay Kit is widely used in research to measure the activity of GST enzymes, which play a critical role in detoxification processes. It is commonly applied in studies focused on understanding cellular defense mechanisms against oxidative stress and toxic substances. This kit is particularly useful in drug development, where it helps assess the efficacy of compounds designed to enhance or inhibit GST activity. Additionally, it is employed in environmental toxicology to evaluate the impact of pollutants on cellular detoxification pathways. The assay is also utilized in clinical research to investigate the relationship between GST activity and diseases such as cancer, neurodegenerative disorders, and liver diseases, providing insights into potential therapeutic targets. Its simplicity and reliability make it a valuable tool for both basic and applied scientific investigations.
