Figure 2From: Immunohistochemical detection of mutations in the epidermal growth factor receptor gene in lung adenocarcinomas using mutation-specific antibodiesPredominant acinar adenocarcinoma with adjacent normal alveoli. A H & E (original magnification x100). B The cytoplasm and membrane of the tumor cells were stained strongly with L858-specific antibody. In contrast, the adjacent normal alveolar epithelial cells were completely negative (original magnification x100).Back to article page
