title: Antibodies to synthetic antibody-combining sites. Antibodies against a surface-simulation peptide with antibody-combining activity toward lysozyme antigenic site 3 react with lysozyme antibodies.
abstract: Recently, we reported the synthesis and immunochemistry of two peptides designed, by complementarity and surface-simulation synthesis, to mimic antibody-combining sites against two antigenic sites of lysozyme. In the present work antibodies were raised against one of these peptides, which is complementary to antigenic site 3 of lysozyme, to determine whether these antibodies will react with anti-lysozyme antibodies. Radioiodinated antipeptide antibodies were bound by immunoadsorbents of the immune IgG from two goats anti-lysozyme antisera but not by adsorbents of myoglobin, non-immune goat IgG or immune IgG of antisera against cytochrome c. The binding of anti-peptide antibodies to adsorbents of anti-lysozyme antibodies was fully inhibited by free lysozyme but not by bovine serum albumin, human hemoglobin A, horse cytochrome c or bovine ribonuclease A. Thus, antisera against an antibody-combining site can be raised by immunizing with a peptide which probably does not exist in the antibody but is designed by surface-simulation synthesis to mimic an antibody-combining site.
