BsAb-armed CIK-mediated cytotoxicity against SK-BR-3. (A) Specific cytotoxicity mediated by CIK cells armed with 0–50 ng antibody per 106 cells (mix, anti-CD3/anti-HER2 equal molar mixture). (B) Specific cytotoxicity of the same batch of CIK cells on two consecutive days. The results shown in the figures were representative of at least two independent experiments.
