This is a graphical representation of the staining pattern. As you can see, the circulating tumor cells are identified by a positive EpCam, positive cytokeratin, and a positive DAPI pattern. In turn, a leukocyte is positive for CD45 and DAPI, but negative for cytokeratin staining. These staining patterns are then used by a trained technologist to interpret images that are presented in a gallery on the Celltracks analyzer.
