Rapid Evaluation of Mutant Exon-11 in c-kit in a Recurrent MCT Case Using CD117 Immunocytofluorescence, FACS-Cell Sorting, and PCR

Figure 3

CD117 immunocytofluorescence has confirmed MCT subpopulation in the aspirate. The nuclei were stained blue by DAPI. Notably, some cells were non-MCT cells because of lack of CD117 immunopositivity in their cytoplasm and on plasma membranes.
