Used in research settings to measure paraoxonase 1 (PON1) enzyme levels in biological samples, particularly in studies related to oxidative stress and cardiovascular health. The kit enables quantification of PON1 activity and concentration in serum or plasma, supporting investigations into metabolic disorders, atherosclerosis, and the impact of environmental toxins. It is also applied in pharmacological studies assessing drug effects on antioxidant enzymes and in epidemiological research linking PON1 levels to disease risk. The ELISA format allows high-throughput, sensitive detection ideal for laboratory analysis.
