  • Reagent including an osmium-containing redox mediator
    Patent number: 5846702
    Abstract: A new group of Os(II) and Os(III) compounds useful as redox mediators in electrochemical biosensors. These compounds have 1) low oxidation potential, 2) fast reaction kinetics between the electroactive center of an enzyme and the compound, 3) slow oxidation of osmium by oxygen, and 4) excellent solubility in aqueous medium. These mediators are particularly useful as a component of a reagent used in an electrochemical biosensor, wherein the biosensor is useful for measuring analytes from a biological fluid, such as blood.
    Type: Grant
    Filed: December 20, 1996
    Date of Patent: December 8, 1998
    Assignee: Boehringer Mannheim Corporation
    Inventors: Zhi David Deng, Gerald F. Sigler, Nigel A. Surridge, Christopher D. Wilsey, Robert J. McEnroe, Walter W. Jernigan, Rebecca W. Muddiman
  • Stable reagent for ferric ion complex indicator systems
    Patent number: 5639631
    Abstract: The invention is a stable reagent used in assay systems that form a colored ferric ion complex, such as Prussian Blue. Such reagents are useful for the detection or measurement of an analyte from a fluid sample. Surprisingly, it has been found that the inclusion of certain ferric ion chelating agents, such as 3-sulfobenzoic acid, will inhibit formation of the blank reaction in the reagent.
    Type: Grant
