  • Patent number: 8012728
    Abstract: The production of a thrombin preparation which is obtained from prothrombin which is, after activation to thrombin without the addition of thromboplastin, purified by a hydrophobic interaction chromatography, it being possible subsequently also to inactivate or remove viruses, is described. Before or after the hydrophobic interaction chromatography it is also possible in addition to carry out a cation exchange chromatography. A thrombin preparation which contains as stabilizer a noncovalently binding inhibitor and to which further stabilizers can be added for stabilization in the liquid state is additionally described.

  • Patent number: 7939288
    Abstract: The invention relates to a method for determining a factor XIII deficiency, a method for determining a fibrinogen deficiency, and a method for differentiating between a factor XIII deficiency and a fibrinogen deficiency by means of thrombelastographic techniques. On the basis of the evaluation of the thrombelastographic parameters, a rapid and a selective substitution of factor XIII and/or of fibrinogen in deficiency states is possible.

  • Patent number: 7939632
    Abstract: The invention relates to therapeutic fusion proteins in which a coagulation factor is fused to a half-life enhancing polypeptide, and in which both are connected by a linker peptide that is proteolytically cleavable. The cleavage of such linkers liberates the coagulation factor from activity-compromising steric hindrance caused by the half-life enhancing polypeptide and thereby allows the generation of fusion proteins may show relatively high molar specific activity when tested in coagulation-related assays. Furthermore, the fact that the linker is cleavable can enhance the rates of inactivation and/or elimination after proteolytic cleavage of the peptide linker compared to the rates measured for corresponding therapeutic fusion proteins linked by the non-cleavable linker having the amino acid sequence GGGGGGV.

  • Patent number: 7863006
    Abstract: This application includes description of antibodies for specifically detecting prions of human origin and methods for detecting pathogenic prions. In some embodiments, the antibodies bind to an epitope characteristic of a human prion protein which is not found in the prion proteins of other species. In some embodiments, the antibodies are not cross-reactive with cow, Syrian Gold hamster, mouse, or rat prions. The application also includes a conformation-dependent immunoassay method for detecting pathogenic prions in a sample containing a prion (PrP) protein. The PrP protein may be present in a first conformation and a second conformation, such as PrPc and PrPSc in which the two conformations have different binding affinity for the antibody used to detect them.
