title: Characterization of idiotypes on antibodies to galactan.
abstract: The correlation between the primary structure and the expression of idiotypy in the anti-galactan antibody system is extremely precise. Amino-acid residues, which are implicated in the expression of recurrent or private idiotopes, are localized in the CDR3 region of all hybridomas and of at least 2 out of 4 myeloma proteins. A single substitution in this region may, in some cases, suffice to abolish idiotope expression.
