NCIt definition : Antigen Targeting involves specific and high affinity non-covalent interaction (binding)
of an antibody reagent through intermolecular physical forces of attraction and spatial
complementarity with a soluble or particulate substance (antigen) that induces an
immune response. Using the keen specificity of antigen recognition by antibodies,
targeting selectively localizes antibody-associated reagents to antigen sites for
therapeutic or diagnostic effect.;
