  • Method and agent for the detection of an analyte containing glycosidic surfactants
    Patent number: 5416001
    Abstract: A method for detecting an analyte is disclosed in which the analyte is brought into contact with at least one receptor which is bound to or can be bound to a solid phase. In order to avoid unspecific interferences the addition of a glycosidic surfactant is proposed.

  • Process for the determination of a component of an immune reaction in a plasma sample
    Patent number: 5068179
    Abstract: The present invention provides a method for the determination of a component of an immune reaction in a plasma sample using an immunoassay at a temperature of from 15.degree. to 40.degree. C., where one of the reactive components is in solid phase. The invention involves adding an amount of plasminogen activator sufficient to eliminate interference by fibrinogen with the component to be determined.

  • Process for stabilizing the activity of peroxidase in solution
    Patent number: 4764468
    Abstract: The present invention provides a process for stabilizing the activity of peroxidase in solution by the addition of a specific activity stabilizer, wherein, to the enzyme present in solid or dissolved form, there is added, as activity stabilizer, phenol which optionally contains one or more substituents selected from lower alkyl radicals and chlorine and bromine atoms, in an amount of from 0.0005 to 2% by weight, referred to the solution.
    Type: Grant
    Filed: March 4, 1986
    Date of Patent: August 16, 1988
    Assignee: Boehringer Mannheim GmbH
    Inventors: Rainer Wehner, Johann Mattersberger, Dagmar Klenner, Gerlinde Deutsch-Weyer
  • Process for the determination of peroxidase
    Patent number: 4752570
    Abstract: The present invention provides a process for the determination of peroxidase by the addition of a peroxide and of a chromogen and measurement of the color resulting from the oxidation of the chromogen, the color formation being stopped after a definite time by the addition of a stop agent, wherein catalase is used as stop agent.
