3. Radioimmunoassays

According to their principle, to achieve a good RIA (competition) or IRMA (sandwich) assay, the reagents and the various reaction steps must meet certain conditions:

  • the substance, Ac or Ag , must be labelled with an appropriate radio-nuclide (iodine, tritium);

  • The Ac antibody used must ensure maximum specificity for the reaction, in particular by using monoclonal antibodies;

  • free and bound fractions must be completely separated, so that only the activity of one or the...
