Lp-PLA2 Recombinant Rabbit mAb (S-3711-113)

Lipoprotein-associated phospholipase A2 (Lp-PLA2), also known as plasma platelet-activating factor acetylhydrolase, is an enzyme encoded by the PLA2G7 gene and belongs to the phospholipase A2 superfamily. It is primarily associated with lipoproteins in the bloodstream and plays a crucial role in lipid metabolism and inflammation. Lp-PLA2 hydrolyzes oxidized phospholipids, such as oxidized low-density lipoprotein (oxLDL), into lysophosphatidylcholine and non-esterified fatty acids, contributing to the progression of atherosclerosis. Additionally, it acts as a biomarker for vascular inflammation and is linked to various cardiovascular diseases. Recent studies have also revealed its involvement in ferroptosis, a form of regulated cell death, where Lp-PLA2 negatively regulates lipid peroxidation and protects cells from ferroptotic cell death.
