Description_x000D_ General description_x000D_ Paraoxonase-1 (PON1) is a member of serum paraoxonases family, consisting of PON1, PON2, and PON3. Human PONs map to the long arm of chromosome 7. PON1 is polymorphic in human populations, and different individuals express widely different levels of this enzyme. PON1 and PON3 are expressed in the liver and secreted into the blood where they are associated with the high-density lipoprotein (HDL) particle._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acids 298-309 of human PON1, conjugated to KLH via an N-terminal cysteine residue. The corresponding sequence differs by one amino acid in mouse and two amino acids in rat. The peptide sequence differs by one amino acid in human PON2 and two amino acids in human PON3._x000D_ Application_x000D_ Anti-Paraoxonase 1 (PON1) antibody produced in rabbit has been used in immunoblotting, and immunofluorescence ._x000D_ Physical form_x000D_ Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Paraoxonase-1 (PON1) protects lipids from oxidation in lipoproteins, macrophages, and erythrocytes. PON1 may confer protection against coronary artery disease by destroying proinflammatory oxidized lipids present in oxidized low-density lipoproteins (LDLs). PON1 plays a key role in the detoxification of organophosphate insecticides such as parathion, chlorpyrifos and diazinon and nerve gases such as soman and sarin.
