Sensitivity of MCF-7 and MCF-7 transfectants towards toxins

MCF-7 control cells and the MCF-7-transfectants were exposed to various concentrations of toxins and their viability assessed 72 hr after toxin addition by MTS cell proliferation assays. The transfectants are less sensitive than controls to the immunotoxin B3(Fv)-PE38KDEL (A), PE (B), and DT (C), but equally sensitive to ricin (D) and cycloheximide (E).
