Figure 1 Immunohistochemical analysis of Elk-1 in paired ESCC samples using anti-Elk-1 antibody (1:100) showing diffuse and strong staining in cytoplasm of esophageal cancer epithelial cells well-differentiated tumor (A), moderately-differentiated tumor (B), sporadic and weak staining in the cytoplasm of normal epithelial cells (C), negative control designed using PBS instead of primary antibody (D), strong staining in nuclei of normal epithelial cells (E) (A-E × 100), and in cytoplasm of well-differentiated esophageal cancer epithelial cells (F) (× 200).
