  • Patent number: 6235535
    Abstract: This invention relates to a fluorescence-based immunoassay method for the detection of an analyte, or for the measurement of its concentration in a biological sample. The method is based on the ability of a multivalent analyte to induce aggregation of receptor molecules labeled with a fluorophore, which molecules are anchored to and are freely mobile on a lipid membrane, and thereby cause changes in the fluorescence.
