Effects of the anti-PD-L1 mAbs on the viability of CT26 colon cancer cells. Effects of PD-L1_1 (grey bar) or anti-mouse PD-L1 (black bar) BioXcell mAb on CT26 colon cancer cells. Cells were treated for 72 h with the anti-PD-L1 mAbs tested at the concentration of 200 nM and cell survival was expressed as percentage of viable cells with respect to untreated cells (a). Representative images of CT26 cells treated as indicated (b). The untreated cells were used as a negative control. Error bars depicted means ± SD. P values for the indicated mAbs relative to untreated cells, are: **P < 0.01, *P < 0.05. Scale bar = 30 μm.
