Abstract
The present invention relates to a process for the immunochemical determination of one or more analytes in a sample using an immobilized specific receptor R1, which exhibits interactive bioaffinity with the analyte, and a specific receptor R2, which likewise exhibits interactive bioaffinity with the analyte and which as a rule is labeled. In the novel process, a receptor R3, which possesses one or more than one specific binding site for the analyte, is added and the resulting immune complexes are entirely or partially dissociated, after which they are reassociated and subsequently detected. According to a further embodiment, a receptor R4 is employed in addition to the receptor R3, which receptor R4 possesses an affinity towards R3 and is immobilized on the solid phase, with the resulting immune complexes being entirely or partially dissociated, after which they are reassociated and subsequently detected.
