  • Reagents, methods and kits for an amphetamine-class fluorescence polarization immunoassy
    Patent number: 5354693
    Abstract: A fluorescence polarization immunoassay (FPIA) for detecting the presence of one or more amphetamine-class analytes in a test sample is provided. The immunoassay uses competition between the analyte and a fluorescently labeled tracer for the binding site on an antibody specific for phenethylamine derivatives. The concentration of amphetamine-class analyte in the sample determines the amount of tracer that binds to the antibody. The amount of tracer-antibody complex formed can be quantitatively measured and is inversely proportional to the quantity of analyte in the test sample. The invention relates to tracers, to immunogens used to elicit antibodies for use as assay reagents, and to assay kits incorporating these tracers and assay reagents.
    Type: Grant
    Filed: June 29, 1993
    Date of Patent: October 11, 1994
    Assignee: Abbott Laboratories
    Inventors: Paul J. Brynes, Donald D. Johnson, Cynthia M. Molina, Charles A. Flentge, Patrick F. Jonas
