Example of (A) before and (B) after picking images acquired at 20x showing CTC recovery from enriched blood sample in the presence of contaminating WBCs. Staining: Red: CK antibody, Green: CD45; Blue: nuclei; (C) Picking of immuno‐magnetically enriched CTCs from a sample deposited onto a specifically developed ALS MagnetPick™ slide installed onto a corresponding slide adapter. The magnetic field created by the adapter prevents cells from moving during the experiment thus facilitating automatic scanning and cell picking. (D) Image of CellSearch enriched blood sample acquired at 10x with combined DAPI and BF illumination showing cell nuclei (bright) and ferromagnetic fluid particles (dark).
