Effect of Rituxan homodimers on sensitivity of DHL-4 and Namalwa/MDR1 cells to RFB4-dgRTA.

(A) Cytotoxic effect of RFB4-dgRTA alone (▾) or IT in combination with Rituxan monomers (●) or homodimers (○). (B) Noncytotoxic effect of RFB4 antibody alone (▾) or in combination with Rituxan monomers (●) or homodimers (○). The protocol described in Figure 5was used here. This is 1 of 2 experiments carried out.
