Abstract: A monoclonal antibody has been developed which only specifically binds activated factor VII, and not factor VII, and which does not bind to an activated factor VII which is complexed with antithrombin III. This monoclonal antibody is isolated from the hybridoma cell line DSM ACC 2332. It can be used for qualitatively and quantitatively detecting factor VIIa in body fluids, blood coagulation preparations or the intermediate stages in the production of these preparations, on cell surfaces or in tissues, and can also be used as a humanized monoclonal antibody in therapeutic preparations.

Abstract: Mutants of the DNA sequence coding for the protease (FSAP) which activates blood clotting factor VII and single-chain plasminogen activators, the mutants comprising a G/C base exchange at nucleotide position 1177 and/or a G/A base exchange at nucleotide position 1601, are described. The corresponding protease has a Glu/Gln exchange at amino acid position 393 and/or a Gly/Glu exchange at amino acid position 534. Diagnostic methods which are used for detecting FSAP in body fluids or tissue cells and also for identifying patients with genetic heterozygous or homozygous FSAP expression are also described. In addition, antibodies against FSAP and its mutants are disclosed and diagnostic methods which can be used to detect antibodies against FSAP and its mutants are specified.

Abstract: The present invention provides antibodies that are specific for the latent or locked form of antithrombin III (AT III). The antibodies have a specificity for latent antithrombin III (1-AT III) that is higher than the specificity for natural AT III. The invention also provides methods of making and 1-AT III. It further provides methods of detecting and quantitating 1-AT III in biological samples.

Abstract: A novel arterial thrombosis risk factor comprising one or more of the identified mutants of coagulation factor VII-activating protease (FSAP) is described. In addition, diagnostic determination methods for detecting these mutants which are identified as risk factors are described.

Abstract: A monoclonal antibody which inhibits the blood clotting factor VII-activating protease and its proenzyme and a blood clotting factor VII-activating protease, stabilized by the addition of said monoclonal antibody, and its proenzyme are described. A suitable monoclonal antibody is produced by hybridoma cell line DSM ACC 2533. The application of the inhibitory, monoclonal antibody in the stabilization of blood clotting preparations and in preparations for reducing the coagulability of the blood is disclosed.

Abstract: Antibodies for specifically detecting pathogenic prions of human origin, and methods for detecting pathogenic prions, are described. In particular, a conformation-dependent immunoassay method for detecting pathogenic prion proteins in a sample of a body fluid, containing a PrP protein, which contains a first, natural, non-pathological conformation, i.e. PrPc, and a second, pathological conformation, i.e.
