Suppression of an AKR lymphoma by antibody and chlorambucil

A cell-surface localizing xenogeneic antibody against an AKR mouse lymphoma of spontaneous origin could be bound to chlorambucil without interference with either the alkylating activity of chlorambucil or the immunologic reactivity of the antibody. Exposure of the lymphoma cells to chlorambucil-bound antibody caused greater tumor inhibition both in vitro and vivo than did the synergistic effect of exposure seperately to the antibody and chlorambucil.
