A transplantable plasmacytoma, TEPC-15 in BALB/c mice, induces a transient antibody response directed against the combining region of the myeloma protein produced by the tumor. Mice immunized with mitomycin-treated tumor cells produce similar antibody but do not develop tumor; mice so immunized survive longer than untreated mice when inoculated with viable TEPC-15 cells. This protection afforded by immunization can be transferred by serum alone; the protective effect of passively given serum is eliminated by absorbing out antibody directed against the myeloma protein.
