The Harry Hood Bassett Flow Cytometry and Small Particles Detection (FCSPD) Facility at UVM is a Larner College of Medicine Core Facility designed as a multi-user resource for the high-speed analysis and sorting of cells. We are located on 1st floor of Firestone Medical Research Building (FMRB), in Firestone RM 161, part of the Center for Biomedical Shared Resources. The FCSPD Facility has BD LSRII and MACSQuant VYB analytical cytometers, and a BD FACS AriaIII high-speed cell sorter. This equipment was purchased through National Institute of Health and UVM-College of Medicine Shared Instrumentation Grants. Investigators who bring samples to the FCSPD Facility for sorting or analysis pay a fee, which is used to offset operating expenses. The FCSPD Facility provides professional consultation and assistance with equipment use, experimental design, and interpretation of flow data.
