  • Patent number: 6258551
    Abstract: The present invention relates to a method of carrying out an immunoassay in a multiphase system. A sample containing an analyte is brought into contact with a receptor A and a tracer. The analyte can either form a complex with the tracer, or counteract the formation of a complex of receptor A and tracer by competing with the tracer for binding to receptor A, or counteract the formation of a complex of receptor A and tracer by competing with receptor A. Receptor B is added and the signal is determined. In this method, receptor A and receptor B are suitably immobilized, ensuring that the tracer either cannot enter into any binding involving the simultaneous participation of receptors A and B or can enter into such a binding to only such a slight extent that it is nevertheless possible to detect and differentiate differing analyte concentrations.
    Type: Grant

  • Patent number: 6013457
    Abstract: The present invention relates to a method of carrying out an immunoassay in a multiphase system. Particularly, a sample containing an analyte is brought into contact with a receptor A and a tracer. The analyte can either from a complex with the tracer, or counteract the formation of a complex of receptor A and tracer by competing with the tracer for binding to receptor A, or counteract the formation of a complex of receptor A and tracer by competing with receptor A. Receptor B is added and the signal is determined. In this method, receptor A and receptor B are suitably immobilized, ensuring that the tracer either cannot enter into any binding involving the simultaneous participation of receptors A and B or can enter into such a binding to only such a slight extent that it is nevertheless possible to detect and differentiate differing analyte concentrations.

    Assignee: Dade Behring Marburg GmbH
    Inventors: Stephan Neuenhofer, Reinhard Kasmarker
  • Patent number: 6010868
    Abstract: The invention concerns a method of stabilizing molecules, or parts of molecules, which are sensitive to hydrolysis, in particular hydrolysis-sensitive labels or label-containing tracers in aqueous solutions. The invention also concerns kits for carrying out immunological assays making use of the method proposed.
    Type: Grant
    Filed: December 20, 1996
    Date of Patent: January 4, 2000
    Assignee: Behring Diagnostics GmbH
    Inventors: Stephan Neuenhofer, Reinhard Kasmarker, Gotz Walter, Hans-Peter Harthus, Gunther Nau, Heinz-Jurgen Skrzipczyk, Peter Molz, Norbert Madry
  • Patent number: 5858668
    Abstract: A homogeneous gene probe test, which is based on altering the signal of the nonhybridized gene probe by a receptor directed against the label on the gene probe is described.
    Type: Grant
    Filed: September 16, 1996
    Date of Patent: January 12, 1999
    Inventors: Stephan Neuenhofer, Heinz-Juergen Skrzipczyk, Norbert Madry, Reinhard Kasmarker, Thomas Leutsch, Eugen Uhlmann
  • Patent number: 5834206
    Abstract: There are disclosed hapten tracer complexes which, on the one hand, contain a hapten which is linked to an indicator component and, on the other hand, an antibody which can bind specifically to the indicator component. These hapten tracer complexes can be employed advantageously in immunoassays.

    Date of Patent: November 10, 1998
    Assignee: Behring Diagnostics GmbH
    Inventors: Stephan Neuenhofer, Reinhard Kasmarker
  • Patent number: 4118468
    Abstract: A diagnostic agent for the visualization of the kidneys is disclosed as well as a process for its manufacture. The new agent consists of pyrrolidinomethyl-tetracycline in a buffer solution, a tin(II) salt and technetium-99m in physiological sodium chloride solution.
