Figure 1

Circulating tumor cells (CTCs) were isolated from the blood of metastatic Triple-negative breast cancer (TNBC) patients using the CellSearch ™ followed by the DEPArray ™ system. (A) CTC were enriched using the CellSearch CTC kit (Veridex) which uses anti-EpCAM conjugated ferrofluid, anti-pan CK-phycoerythrin (PE), anti-CD45-allophyocyanin (APC) and 4′, 6 diamidino 2 phenylindole for nuclear staining. (B) Single CTCs, clusters of CTCs and single white blood cells (WBCs; used as controls) were selected and isolated on the DEPArray™ System. Two single CTCs and a big CTC cluster selected from a triple-negative patient (TRF106811/6146) are shown. In the upper part of the figure, the anti- EpCAM and anti-CK antibodies are represented by blue and yellow circles, respectively, around a epithelial cell; the anti-CD45 antibodies are represented by pink circles around a leukocyte.
