Immunoassay for toxic congeners of polychlorinated biphenyls

摘要

The present invention provides a method for determining qualitatively or quantitatively the presence of toxic congeners of polychlorinated biphenyl in a test sample. The method includes the steps of: providing a known quantity of antibodies to the toxic polychlorinated biphenyl congener; providing a competitor that will bind to said antibodies in competition with the toxic polychlorinated biphenyl congener and having a lower affinity to said antibodies than said antibodies have to the toxic polychlorinated biphenyl congener; incubating said antibodies and said competitor in the presence of a test sample; and detecting the presence of the toxic polychlorinated biphenyl toxic congener in the test sample.
