    摘要: The present invention provides a novel antithrombotic antibody, the antibody uses FIXa as a target and has unique properties, and specifically targets the binding site of coagulation factor FIXa and FVIIIa, reduces the formation of a FVIIa-FIXa complex, blocks the conversion of FX to FXa, and thereby exerts an antithrombotic effect. The antibody of the present invention has suitable antithrombotic properties, and has a large effective therapeutic concentration window, but does not increase the risk of bleeding in addition, the antibody can meet the needs for suitable antithrombotic performance in clinical application and for effective avoidance of problems regarding bleeding caused by excessive effects. The present invention also discloses a method for screening drugs by using an FIXa-FVIIIa binding site as a target.
