Staining with PD-L1 monoclonal antibodies in TNBC. PD-L1 expression in cancer cells was similarly positive for PD-L1 (clone 28-8) and PD-L1 (clone E1L3N) antibodies, but low for PD-L1 (clone SP142). Both PD-L1 (clone 28-8) and PD-L1 (clone E1L3N) stained positive in many immune cells, while PD-L1 (clone SP142) was mostly negative in this cell type. Placenta and tonsil tissue were used as the positive control
