Used in research to quantify levels of Glutathione Peroxidase 4 (GPX4) in biological samples such as cell lysates, tissue homogenates, and serum. GPX4 is a key enzyme in protecting cells from oxidative damage and lipid peroxidation, making this kit essential in studies related to oxidative stress, ferroptosis, neurodegenerative diseases, cancer, and inflammatory conditions. The ELISA format allows for sensitive and specific detection, enabling researchers to monitor changes in GPX4 expression under different experimental or pathological conditions. Widely used in academic, pharmaceutical, and biomedical research settings to support mechanistic studies and drug development.
