An immunoassay, utilizing an active support capable of interacting with a substantially colorless product, formed in a reaction between an enzyme-labeled productive complex and enzyme substrates, for form a signal-emitting product associated with the support, is provided. The productive complex is formed between an immune complex of an analyte with its enzyme-labeled antibody and an enzyme-labeled complement component. The immune complex is either formed or collected on the active support during the assay. The assay is useful for the detection and measurement of analytes in biological samples.
