Description générale

Recombinant PAF-AH is a 420 amino acid glycoprotein which migrates with an apparent molecular mass of 47-55kDa by SDS-PAGE analysis.

Actions biochimiques/physiologiques

Platelet Activating Factor (PAF) is a biologically active phospholipid, which exerts primarily proinflammatory activities by specifically signaling through G-protein-coupled receptors on platelets, neutrophils, and monocytes. Platelet activating factor acetylhydrolase (PAF-AH) is a secreted protein that mediates PAF activity by specifically catalyzing hydrolysis of the "sn2" ester bond, resulting in the conversion of PAF to the biologically inactive lyso-PAF. PAF-AH can also interact with LDL (low density lipoprotein) particles to induce the hydrolysis of LDL associated, oxidized phospholipids, generating lysophosphatidylcholine (lyso-PC) and other lysophospholipids. High levels of PAF-AH in plasma can be an indication of resistant hypertension. Polymorphism in PAF-AH gene at A379V might be linked with ischemic stroke susceptibility.

Forme physique

Lyophilized from 10 mM Tris, pH 8.5.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
