A method for detecting the presence of a high-molecular-weight analyte, which uses a variation on complementation assays, comprising (1) providing an enzyme donor (ED)complex comprising ED coupled to an analyte-specific binding molecule, wherein the ED complex retains measurable complementation activity such that active .beta.-galactosidase is formed in the presence of an enzyme acceptor (EA); (2) contacting the ED complex and EA in the presence of a sample suspected of containing a high-molecular-weight analyte that reacts specifically with the analyte-specific binding molecule; and (3) relating the presence of the analyte in the sample to the formation of active .beta.-galactosidase enzyme.
