PD-L1 (SP263) antibody staining in tumor tissue samples. Photomicrographs of PD-L1 (SP263) staining in NSCLC and HNSCC tissue, demonstrating the range of PD-L1 staining intensity and frequency obtained with the PD-L1 (SP263) assay on NSCLC (a-d) and HNSCC (e-h) samples. a, e negative tumor cells (20X), positive immune cells; b, f (10X): low tumor staining; c, g (10X): moderate tumor staining; d, h (10X,20X): high tumor staining. HNSCC head and neck squamous cell carcinoma, NSCLC non-small cell lung cancer, PD-L1 programmed cell death ligand-1
