  • Mutants of human antithrobin III and methods for their production
    Patent number: 5700663
    Abstract: Mutants of AT III which have been advantageously modified at one or more potential glycosylation sites or at the Arg393 position are described. As a rule, combination of the mutations enhances the advantageous modifications.
    Type: Grant
    Filed: May 30, 1995
    Date of Patent: December 23, 1997
    Assignee: Behringwerke Aktiengesellschaft
    Inventors: Gerd Zettlmeissl, Hermann Erich Karges, Achim Becker
  • Quantitative determination of antithrombin III
    Patent number: 4106990
    Abstract: Antithrombin III in plasma or serum is determined by combining diluted plasma or serum with heparin or heparinoids and thrombin to form a mixture, permitting the mixture to stand, thereafter adding to the mixture a fibrinogen solution and determining the coagulation time. The heparin or heparinoids and thrombin can be combined together to form a reagent for use in the determination.
    Type: Grant
    Filed: June 10, 1976
    Date of Patent: August 15, 1978
    Assignee: Behringwerke Aktiengesellschaft
    Inventors: Hermann Erich Karges, Norbert Heimburger
  • Process for the determination of plasminogen
    Patent number: 4033824
    Abstract: The invention relates to a process for the analytical determination of human plasminogen which comprises mixing a liquid containing diluted human plasminogen withA. a catalyst, such as streptokinase, converting human plasminogen into human plasminogen activator,B. fibrinogen andC. a plasminogen, such as the plasminogen of a ruminant, e.g. bovine plasminogen, which cannot be activated by the catalyst andD. thrombinAnd determining the coagulation of the mixture.
    Type: Grant
