In vitro method of determining the biological activity of factor Xa inhibitor in blood

摘要

The present invention concerns an in vitro method for the determination of the plasma inhibitor to activated Factor X (XaI), which is an alpha-2-globulin of molecular weight 58,000-65,000, and which has been termed variously as antithrombin III, heparin cofactor and alpha-2-antitrypsin.
