Figure 1 Circulating tumour cells are separated from the leucocytes using magnetic beads coupled with epithelial cell adhesion molecule antibody and a magnetic device. These complexes are then tagged with cytokeratin-19 (CK19) biotinylated antibody and streptavidin-conjugated quantum dots (QDs) which lead to the detection of a fluorescent signal. EpCAM: Epithelial cell adhesion molecule; DLD-1: Human colon adenocarcinoma cell line.
