The mission of the Flow Cytometry & Cell Sorting Shared Resource (FCSR) is to provide flow and mass cytometry services to the GUMC research community, and the NCI-designated Georgetown Lombardi Comprehensive Cancer Center (LCCC) Research Consortium.  Within this Consortium, the FCSR provides comprehensive flow analysis and cell sorting capabilities to researchers at both the LCCC in Washington, DC, and the John Theurer Cancer Center in New Jersey, which includes research at the Hackensack Meridian Center for Discovery and Innovation. In addition, the Fluidigm Hyperion, capable of CyTOF and imaging mass cytometry, and the Malvern NanoSight for nanoparticle analysis are available to our research consortium. Technical services and training through the FCSR include assistance in panel and experimental design and data analysis.
