Shared Idiotypes Expressed by Human B-Cell Lymphomas

Abstract
Each B-cell lymphoma expresses a surface immunoglobulin that contains unique antigenic determinants (idiotypes). We have produced 199 murine monoclonal antibodies reactive with the idiotypes isolated from 67 patients with follicular small-cleaved-cell lymphoma. These antiidiotype antibodies were analyzed for their ability to react with lymphoma cells from patients other than the one against which each antibody was made.
