  • 3-methoxy-4-hydroxyphenylglycol fluorescence polarization immunoassay and conjugates
    Patent number: 5372949
    Abstract: The present invention is directed to a fluorescence polarization immunoassay for determining the 3-methoxy-4-hydroxyphenylglycol content in body fluids, to the various components needed for preparing and carrying out such an assay, and to methods of making these components. Specifically, tracers, immunogens and antibodies are disclosed, as well as methods for preparing them. The assay is conducted by measuring the degree of polarization of plane polarized light that has been passed through a sample containing antiserum and tracer.
    Type: Grant
    Filed: September 3, 1992
    Date of Patent: December 13, 1994
    Assignee: Abbott Laboratories
    Inventors: Christine H. Zeitvogel, Maciej B. Adamczyk, David A. Betebenner, Kenward S. Vaughan
