Reagents and an immunoassay for detecting the presence or amount of polychlorinated biphenyls in a test sample. The assay is performed by adding a known concentration of a tracer labeled with a detectable moiety and a known concentration of an analyte-specific antibody to a test sample to form a mixture, incubating the mixture to form labeled tracer-antibody and analyte-antibody complexes, and determining the presence or amount of tracer-antibody complexes formed as a measure of the presence or amount of analyte in the test sample. Reagents provided include tracers, immunogens and an additive compound useful in preventing non-specific binding of the polychlorinated biphenyls to proteins which may be present |
