    摘要: A virus-inactivated Factor-Xa preparation with at least 100 units coagulation factor activity per mg protein is described, wherein this preparation is produced by activation of a corresponding starting material and subsequent treatment for the inactivation of infectious agents, particularly viruses. By incubation, the preparation obtained in this manner is transformed into a stable beta-Factor Xa preparation. In addition, the use of the present preparation for the treatment of hemophilia A inhibitor patients is disclosed.

    摘要: The invention provides a kit for measuring the thrombin generation in a sample of a patient's blood or plasma, or in a sample of clotting factors. The kit contains lyophilized tissue factor/phospholipid-complex and a lyophilized mixture containing a thrombin-substrate and CaCl2. The invention also provides processes for preparing the reagents for the kit. The kit can be used in a method for measuring the thrombin generation in a sample, wherein it is possible to detect changes in thrombin generation kinetics, for example after administration of inhibitor bypassing agents to a patient who has developed inhibitors to an exogenous clotting factor such as Factor VIII.

    摘要: The present invention relates to a method for the purification of alpha-1 proteinase inhibitor (a1PI) from protein fractions. More specifically, the invention relates to an improved method for the purification of alpha-1 proteinase inhibitor (a1PI), wherein the yield of a1PI can be increased by thawing the starting material and incubating it for several hours before subjecting it to a washing step.
