Immunohistochemical staining of cytoplastic EGFR in normal parenchymal and RCC tissues. Tissue sections of normal parenchymal tissues (A, C) or RCC (B, D) were from the same patient. The polyclonal anti-EGFR antibody was used to stain paraffin sections (A, B). Negative control was the omission of the primary antibody (C, D). The breast cancer used as a positive control for EGFR expression (E). Original magnification, × 200.
