Flow Cytometry & Cell Sorting

Shared Resource


The Georgetown Lombardi Comprehensive Cancer Center Flow Cytometry & Cell Sorting Shared Resource (FCSR) provides flow cytometry and fluorescence activated cell sorting (FACS) in a variety of research applications at Georgetown University.

Karen Creswell, PhD, director of the facility, has extensive experience with flow cytometry and cell sorting including immunofluorescence methods, DNA histogram/cell cycle analysis, and sterile cell sorting, and is available for development of specific applications. A full-time instrument operator also provides for comprehensive support of this technology. Approximately 50 investigators use this facility annually.

More information on FCSR services and capabilities is available on LombardiNet.

New shared resource facility users must schedule their first experiment with Dr. Creswell. Thereafter, experiments may be scheduled by the instrument operator. Currently, it is necessary to schedule experiments one week in advance in order to obtain a specific day and time.

All Georgetown University investigators may use the Flow Cytometry and Cell Sorting Shared Resource.
