Abstract

Anti-idiotypic (anti-Id) antibodies were raised against two murine monoclonal antibodies (mAb 1/1 and mAb 2/1) which recognise two distinct and well-characterised epitopes on a 24-residue synthetic peptide representing part of the haemagglutinin (HA) of influenza virus. A monoclonal anti-Id antibody, specific for mAb 2/1, could bind to mAb 2/1 when the paratope of the latter was occupied with peptide, indicating that this anti-Id antibody is directed to a framework idiotope. In contrast, an anti-Id mAb derived from mAb 1/1-immunised mice was inhibited in its binding to Id by the parent peptide and also by the heptapeptide NVPEKQT which constitutes the epitope recognised by mAb 1/1. The small..
