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 in the test sample. A kit for performing the assay also is provided.
试剂和一种免疫测定用于检测测试样品中多氯联苯的存在或数量。该测定是通过向测试样品中添加已知浓度的带有可检测基团的示踪剂和已知浓度的特异性抗体来形成混合物,孵育混合物以形成标记的示踪剂-抗体和分析物-抗体复合物,并测定形成的示踪剂-抗体复合物的存在或数量作为测试样品中分析物存在或数量的测量。提供的试剂包括示踪剂、免疫原和一种有用的添加剂化合物,可防止多氯联苯与可能存在于测试样品中的蛋白质发生非特异性结合。还提供了用于执行该测定的试剂盒。
