Chemical synthesis of idiotopes. Evidence that antisera to the same JH1 peptide detect multiple binding site-associated idiotopes.
In an attempt to better understand the molecular basis of idiotypy, we have generated several site-specific antisera through immunization of animals with synthetic peptides corresponding to the (JH1) heavy chain joining segment 1 of the mouse heavy chain variable (VH) region. These anti-peptide sera identify several idiotypic determinants present on intact hybridoma and myeloma immunoglobulins. Expression of at least three of these idiotopes is correlated with the antigen specificity of the family of immunoglobulins bearing the determinant. Use of synthetic peptides may prove a powerful technique in the generation of molecularly defined antiidiotypic reagents.
