Tissue Expression of Low and High Molecular Weight Cytokeratins in Lung Carcinoma Sections: Its Correlation with Some Clinic-Pathological Features

Figure 2

Microphotographs of squamous carcinoma of the lung. (a) Hematoxylin and eosin coloration. Immunohistochemical localization of cytokeratin was performed by means of MNF116 (reacts with cytokeratins 5, 6, 8, 17, and probably also 19) and 34βE12 antibodies (reacts with high molecular weight cytokeratins 1, 5, 10, and 14). Observe the intense reactivity of these Mabs located mainly in the cytoplasm of malignant epithelial cells. Conventional immunoperoxidase technique counterstaining with Carrazzi hematoxylin. Black bar = 50 μm.
