Affinity Column Mediated Immunoenzymometric Assays

  • J. William Freytag


Immunometric assays, by definition, are immunoassays configured in such a way that labeled-antibodies are utilized as the quantifying entity. This is in contrast to competitive radioimmunoassays or enzyme-immunoassays in which labeled-antigens are utilized in competition with sample antigen to bind to a limited number of antibody sites. The label applied to the antibody can take the form of a radioisotope, enzyme, fluorophore, luminescent tag, or almost any tag ultimately capable of generating a signal, even through some complex coupling mechanism. Two fundamentally different immunometric assay configurations have been described: the one-site immunometric assay and the two site (sandwich) immunometric assay.
