Abstract
Compositions and methods are disclosed for multiple simultaneous assays of different analytes using radioactive labeled antibodies to the analytes, at least one portion of the assay being an immunoradiometric assay in which there is employed a metal isotope label, e.g., .sup.57 Co, attached to an antibody to the analyte through a chelator, e.g., ethylenediaminetetraacetic acid. Multiple simultaneous immunoradiometric assays can be performed by this method, as can multiple simultaneous assays in which one portion of the assay is an immunoradiometric assay and another portion or portions involve one or more other radioassay techniques.
