PON1: ELISA Kits

PON (paraoxonase/lactonase) family members PON1, PON2 and PON3 are calcium-dependent antioxidant enzymes. PON1 is secreted into the bloodstream associated with high-density lipoproteins (HDL). Serum PON1 concentrations vary widely among normal individuals, in part due to differential expression of some polymorphisms. The antioxidant activity of PON1 and other PON members may slow the initiation and progression of atherosclerosis.
