BALB/c mice immunized with myeloma proteins 315 or 460 made antibodies to the
individually specific (“idiotypic”) determinants of these proteins and suppressed growth of
the corresponding transplanted tumor cells (MOPC-315 or MOPC-460). Stable, variant
MOPC-315 tumors that produce only the light chain of protein 315 grew in several of the
mice immunized with this protein, probably because the anti-idiotypic immune response
selects against those myeloma cells that form the intact myeloma protein.
