From: PD-L1 expression and the prognostic significance in gastric cancer: a retrospective comparison of three PD-L1 antibody clones (SP142, 28–8 and E1L3N)

Fig. 1

Representative photomicrographs of PD-L1 expression in tonsil tissue and GC. All three antibodies (clone SP142, 28–8 and E1L3N) showed a similar, predominantly membrane staining pattern in tonsil tissues (a-c) and GC (d-f). One specimen showed weak positive staining for clone SP142, but negative staining for clones 28–8 and E1L3N (g-i). The original magnification of all images is 400×. GC, gastric cancer; PD-L1, programmed death ligand 1
