DefinitionThis section has been translated automatically.

The alpha-2-macroglobulin is a coagulation inhibitor, which is present in the plasma in a concentration of 150-300mg/dl. Its molecular weight is 725,000 D. It is synthesized in the liver and has a half-life of about two to three days. Furthermore, the alpha-2-macroglobulin converts the complex of antithrombin III with the activated serine proteases into a stable compound and inhibits factor Xa. It does not competitively inactivate plasmin. It is located in the plasma and on the platelet membrane.
