  • Antibody-selective membrane electrodes
    Patent number: 4402819
    Abstract: An antibody-selective potentiometric electrode for the quantitative determination of antibodies in dilute liquid serum samples employing an insoluble membrane incorporating an antigen having bonded thereto an ion carrier effecting the permeability of preselected cations therein, which permeability is a function of specific antibody concentrations in analysis, and the corresponding method of analysis.
    Type: Grant
    Filed: October 21, 1981
    Date of Patent: September 6, 1983
    Assignee: University of Delaware
    Inventors: Garry A. Rechnitz, Robert L. Solsky
  • Bio-selective electrode probes using tissue slices
    Patent number: 4216065
    Abstract: A bio-selective potentiometric electrode probe for the determination of amino acid concentrations in aqueous liquids comprising an ammonia gas analytical electrode provided at its tip with a closely adjacent thin layer of a fresh animal tissue containing, as a natural constituent thereof, an enzyme effective to catalyze degradation of the specific amino acid in analysis to either ammonia or to an intermediate compound subject to further degradation to ammonia by an additional enzyme, which ammonia is a function of the amino acid concentration in the liquid.
