    2-4 RIA solid phase method

    Immunoradiometric assay (IRMA)
    IRMA is one of the techniques of RIA. Antibodies linked to the solid phase are reacted with antigens that are secondarily reacted with antibodies labeled with radioactive isotope (RI).
    This is also called as the sandwich technique, because the solid-phase linked antibodies and the RI-labeled antibodies bind to the antigens, respectively, forming an antigen sandwich.
