Used in research settings to quantify levels of Glutathione Peroxidase 4 (GPX4) in biological samples such as cell lysates, tissue homogenates, and serum. This ELISA kit enables scientists to study the role of GPX4 in oxidative stress, lipid peroxidation, and ferroptosis—a form of regulated cell death linked to neurodegenerative diseases, cancer, and inflammatory conditions. It is widely applied in drug development and mechanistic studies where modulation of antioxidant defenses is critical. The 96-well format allows high-throughput screening, making it suitable for both academic and pharmaceutical research.
