Representative images of immunostaining for CD73 in TMA cores from patients in the AZURE study. (A) Images of protein expression obtained using the anti-CD73 antibody and visualized at a magnification of 20x. Score 0–3 categories were determined by the intensity of staining in the cytoplasmic compartment of tumor cells only. Scale bar = 200 μm. (B) 40x magnification view of from the boxed regions depicted in panel A. Scale bar of core view = 100 μm. Scale bar of 40x = 50 μm.
