Product Overview
This rabbit polyclonal antibody detects serum paraoxonase/arylesterase 2 (gene PON2) in human samples and is validated for Western blot, flow cytometry and ELISA. The predicted molecular weight is 39.4 kDa; the supplier reports observed bands at 39, 40 kDa.
Paraoxonase 2 (PON2) is an intracellular member of the paraoxonase family that is widely expressed but, unlike PON1, is not carried on HDL. It hydrolyzes certain lactones and shows antioxidant activity, reducing lipid peroxidation of LDL. PON2 is studied in oxidative stress, atherosclerosis and bacterial quorum-sensing signals.

Immunogen
Recombinant human PON2 fragment (Asp38–Asp337), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human. UniProt places serum paraoxonase/arylesterase 2 in the membrane. Tissue expression noted by UniProt (human): Widely expressed with highest expression in liver, lung, placenta, testis and heart. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
