Figure 4 Summary of the technique for producing monoclonal antibodies by hybridizing myeloma tumor cells with normal plasma cells.

FIGURE 5. The mechanism of an immunotoxin. A potential therapy for cancer and immune dysfunctions is the use of a monoclonal antibody specific for a certain tumor that carries a potent toxin molecule. The antibody would circulate to cancer cells and deliver the toxin to them. Normal body cells would be unharmed.
