Abstract

Homogeneous immunoassay employing a light absorbing particle to which a member of an immunological pair (mip)-ligand and antiligand is bound and a labeled mip, where the label is light emitting. The labeled mip becomes bound to the light absorbing particle in proportion to the amount of analyte in the assay medium. Thus, the light emitted from the medium is related to the amount of analyte in the medium.
