Expression of EGFR protein in lung SCC cells, lung ADC cells and the control of non-cancerous lung tissue were detected by IHC using specific antibody as described in the section of materials and methods.
<p>Strong positive staining of EGFR protein was found in cell membranes and cytoplasm of lung SCC and lung ADC cells (Fig 2A and 2B, 20×, IHC, DAB staining). Negative staining of EGFR was showed in non-cancerous lung tissue (Fig 2C, 20×, IHC, DAB staining). Negative control showed no EGFR staining in the lung SCC cells (Fig 2D, 20×, IHC, DAB staining).</p
