Immunoreactivity of the 14F7 Mab (Raised against N-Glycolyl GM3 Ganglioside) as a Positive Prognostic Factor in Non-Small-Cell Lung Cancer
Figure 1
Microphotographs of poorly differentiated adenocarcinoma of the lung. (a) Hematoxylin and eosin coloration. Immunohistochemical localization of cytokeratin was performed to verify the quality of the formalin-fixed and paraffin-embedded tissues. (b) Conventional immunoperoxidase techique counterstaining with Mayer’s Hematoxylin. Black bar = 50 μm. (c) and (d) Conventional fluorescent and confocal microscopy, respectively. FITC-labeled cytokeratin (green signal) was used. Nuclei were contrasted with propidium iodide (red signal) (40 and 100x magnification, resp.).
