  • Chemiluminescent reagent and assay using a substituted acetanilide for light generation
    Patent number: 5705357
    Abstract: A simplified composition for generating a chemiluminescent signal in the presence of a peroxidase includes a substituted acetanilide as the sole light-producing substrate for the peroxidase. Assays for various analytes can be carried out with this composition at near neutral pH, exhibit low background and are highly sensitive.
    Type: Grant
    Filed: August 29, 1994
    Date of Patent: January 6, 1998
    Assignee: Johnson & Johnson Clinical Diagnostics, Inc.
    Inventors: Thomas Robert Kissel, Alan E. Friedman, Sarah A. Fingar
  • Use of 4'-hydroxy- and 4'-alkoxy-substituted electron transfer agents in compositions, elements, test kits and analytical methods
    Patent number: 5372931
    Abstract: Aqueous compositions, test kits, test devices and methods can be used to detect hydrogen peroxide or peroxidase by generating a colorimetric or chemiluminescent signal in the presence of the analyte. Signal generation is enhanced by the presence of certain substituted 4-hydroxy- or 4-alkoxy-substituted phenyl or naphthyl electron transfer agents.

    Inventors: Alan E. Friedman, Thomas R. Kissel
  • Analytical element and method for the determination of a specific binding ligand using a 4-hydroxy or 4-alkoxyarylacetamide as stabilizer
    Patent number: 5372932
    Abstract: A dry analytical element can be used to sensitively and rapidly detect a wide variety of specific binding ligands in either a competitive binding or sandwich assay format. The assays are carried out using a peroxidase-labeled immunoreactant. The peroxidase label is stabilized with a 4-hydroxy or 4-alkoxyarylacetamide which is located in one or more zones of the element. Not only is the label stabilized with the stabilizer, but the assay is more sensitive.
