Abstract
The presence of an antigenic analyte ligand in a liquid sample is determined by (1) mixing the sample with a fluorescently labeled ligand immunologically complexed onto a solid phase supported antibody capable of exchanging the fluorescently labeled ligand with the analyte ligand in the sample and (2) measuring the fluorescence of the resulting liquid phase without measuring the fluorescence of the resulting solid phase and without separating the resulting solid phase from the resulting liquid phase.
