  • Fluorescence polarazation immunoassay for tetrahydrocannabinoids
    Patent number: 5463027
    Abstract: This disclosure related to a method and reagents for determining tetrahydrocannabinoids (THC) and THC metabolites in a biological fluid such as urine. In particular, this disclosure relates to a fluorescence polarization immunoassay procedure for determining the presence of THC and to a novel class of tracer compounds employed as reagents in such procedures. The procedure described also provides for novel wash reagent for a THC fluorescence polarization assay.
    Type: Grant
    Filed: August 10, 1994

  • Methadone fluorescence polarization immunoassay
    Patent number: 5073629
    Abstract: A fluorescence polarization immunoassay for detecting the presence of methadone in a test sample is provided, based upon competition between methadone and a fluorescently labeled tracer for the binding sites on an antibody specific for methadone. The concentration of methadone 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 methadone in the sample. Tracers used as reagents and immunogens used to raise antibodies for use as reagents are also disclosed.
