Characterization of the CTC cell line CTC-ITB-01, analyses by Western Blot using three biological replicates.A: Determination of the epithelial phenotype.B: Analysis of receptor tyrosine kinase signaling.C: Other breast cancer relevant proteins.D: Growth curves of the denoted cell lines. At the time point 0 h, 40,000 cells of each cell lines were counted and were set to 100. Vertical error bars show the standard deviation of three independent measurements. Uncropped X-ray film images are shown in supplementary information.
