Expression of ErbB family receptors in A549 human lung tumor cell line. A549 cell line is positive for EGFR (red labeling) (A), and ErbB2 (green) (B) and negative for ErbB3 (C) and ErbB4 (D) (FITC staining, green), respectively, in immunofluorescence analysis. DAPI staining (blue) indicates the localization of nuclei. One representative image from three independent experiments is presented.
