Abstract
This invention provides a two-site immunoassay method for a ligand utilizing a single incubation. The multivalent ligand, labeled receptor for the ligand and unlabeled receptor for the ligand covalently bound to a solid-phase support are incubated as a substantially stable suspension to produce a solid and liquid phase. The solid and liquid phases are separated from each other and the labeled receptor in either phase is quantitated. The method may be used to assay for human thyroid stimulating hormone using purified, radioactively labeled antibodies and unlabeled antibodies covalently bound to hydrolyzed polyacrylamide particles.
