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
用于检测测试样品中是否存在多氯联苯或其含量的试剂和免疫测定法。检测方法是将已知浓度的标记有可检测分子的示踪剂和已知浓度的分析物特异性抗体添加到测试样品中形成混合物,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,并确定所形成的示踪剂-抗体复合物的存在或数量,以此来衡量测试样品中分析物的存在或数量。所提供的试剂包括示踪剂、免疫原和一种添加剂化合物,可防止多氯联苯与可能存在的蛋白质发生非特异性结合。
