Used in biomedical research to measure paraoxonase (PON) enzyme activity in human serum or plasma samples. Helps assess antioxidant capacity and lipid metabolism, which are linked to cardiovascular health. Widely applied in studies related to atherosclerosis, diabetes, and oxidative stress. Enables researchers to evaluate PON levels as a potential biomarker for inflammatory or metabolic disorders. Suitable for use in clinical labs and research settings where enzyme-linked immunoassays are performed.
