Overview of the method. Enriched CTCs were collected after CellSearch analysis using the Profile or Epithelial cell kit. The solution containing CTCs and leukocytes was placed in a magnetic tray. Following incubation, the non-adherent solvent was removed and the ferrofluid-attached cells were re-suspended in a smaller volume of PBS, thus permitting further enrichment. This solution was dropped and fixed on a glass slide before subsequent staining according to protocols 1 or 2. Visualization is possible with a fluorescence or bright-field microscope, depending on the staining method applied.
