Used in biomedical research to measure levels of glutathione peroxidase enzyme in human samples, this kit enables assessment of antioxidant activity in cells and tissues. It is commonly applied in studies related to oxidative stress, such as in diabetes, cardiovascular diseases, neurodegenerative disorders, and liver dysfunction. Researchers use it to evaluate how diseases or treatments affect the body's antioxidant defenses. The assay supports quantitative analysis in serum, plasma, and cell lysates, making it valuable in clinical labs and pharmaceutical research for monitoring disease progression and response to therapy.
