WebA placenta protein, originally termed PP4, was found to inhibit the aPTT in a concentration-dependent manner. PP4 which turned out to be identical with a vascular anticoagulant of the annexin type, inhibits the blood clotting process by binding of the essential lipids in a reaction which is dependent on calcium ions. Also in the presence of calcium PP4 … WebExcess calcium and kaolin and phospholipids (both of which have a negative charge that mimics the negative charge of collagen that begins the intrinsic pathway) are added to the citrated plasma and then the time it takes to clot is measured.
