From: Detection of erbB2 copy number variations in plasma of patients with esophageal carcinoma
Isolation of CTCs using fluorescence-activated cell sorting. (A, B) Scatter plots for gating of cells positive to CK8, CK18, CK19 and EpCAM in the MDA-231T breast cancer cell line (A; positive control) and from the blood of a representative patient with EC (B). (C) Histogram showing erbB2 CN variations from sorting CTCs of patients with EC compared to the CN of DNA from plasma of the same patients. Data are representative of three independent experiments.
