ABSTRACT:
The invention concerns a method for the determination of an analyte in a sample liquid wherein the sample liquid is incubated with (a) a first receptor which binds to a first epitope that is only present once on the analyte and is immobilized on a particulate carrier material and (b) a second receptor which binds to a second epitope on the analyte and has at least two binding sites for the second epitope, the first epitope being different from the second epitope and the analyte is determined by means of the binding to both receptors.
