Expression of Prdx1 in ESCC, adjacent ESCC and normal tissues by immunohistochemistry. The polyclonal anti-Prdx1 antibody was used as the primary antibody to detect the expression of Prdx1 in ESCC, adjacent ESCC and normal esophagus tissues. (A) A representative normal esophageal tissue with anti-Prdx-negative staining (magnification, ×40). (B) A representative adjacent ESCC tissue with anti-Prdx1-negative staining (magnification, ×40). (C) A representative adjacent ESCC tissue with strong positive staining (magnification, ×40). (D) A representative ESCC tissue with strong positive staining (magnification, ×40). Prdx1, peroxiredoxin 1; ESCC, esophageal squamous cell carcinoma.
