Figure 1From: Expression of the epidermal growth factor receptor (EGFR) and the phosphorylated EGFR in invasive breast carcinomasImmunohistochemisty of EGFR and pEGFR in invasive breast carcinoma. Intense membrane staining of (a) EGFR (ABC/HRPX200) and of (b) pEGFR (ABC/HRPX400) in two cases of invasive ductal breast carcinoma. EGFR, epidermal growth factor receptor; pEGFR, phosphorylated epidermal growth factor receptor.Back to article page
