Patents by Inventor Heidi L. Woerner

Heidi L. Woerner has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Stabilization of HOunder alkaline conditions for use in luminescence, fluorescence and colorimetric assays for enhanced detection of peroxidase type assays
    Patent number: 7563566
    Abstract: The invention relates to stannous halide stabilized and/or enhanced alkaline solutions to be used in combination with calorimetric, luminescent and fluorescent assays. The buffered solutions stabilize hydrogen peroxide at a pH greater than 7.0 and preferably greater than 9.0. By stabilizing and/or enhancing hydrogen peroxide in the buffer system, the compositions used in such assays may have a higher shelf-life and provide enhanced detection of the subject analyte.
    Type: Grant
    Filed: January 3, 2007
    Date of Patent: July 21, 2009
    Assignee: SurModics, Inc.
    Inventors: Thomas M. Woerner, Joseph A. Rosebrock, Charles W. Hewitt, Heidi L. Woerner
