Used in biomedical research to measure glutathione peroxidase 3 (GPX3) levels in human biological samples such as plasma, serum, and urine. It helps assess antioxidant activity and oxidative stress in studies related to inflammation, cardiovascular diseases, kidney disorders, and cancer. The kit enables quantitative detection of GPX3 protein, supporting research into disease mechanisms, biomarker discovery, and evaluation of therapeutic interventions targeting redox balance. Widely used in clinical labs and research settings due to its sensitivity, specificity, and ease of use in enzyme-linked immunosorbent assay (ELISA) format.
