Used for measuring glutathione peroxidase (GSH-PX) enzyme activity in human biological samples such as serum, plasma, or tissue homogenates. It is widely applied in clinical research and diagnostic laboratories to assess oxidative stress levels in patients. This kit helps in studying diseases linked to oxidative damage, including cardiovascular disorders, neurodegenerative diseases like Alzheimer's and Parkinson's, diabetes, and chronic inflammation. It is also used in monitoring antioxidant status and evaluating the effectiveness of antioxidant therapies. The assay enables high-throughput, accurate quantification of enzyme activity, making it valuable in both research and medical testing settings.
