City of Hope’s Analytical Cytometry Core (ACC) Facility provides researchers with high-quality flow cytometry instrumentation, as well as expertise in analyzing and/or sorting sample populations of interest via interpretation of their physical, fluorescent and/or light-scattering properties. The facilities and their services are available to both City of Hope and non-City of Hope researchers.
The Analytical Cytometry Core has 7 cell sorters (ARIA III, 4-ARIA Fusion, and ARIA II SORP, and Tyto Cell Sorter) and 16 analyzers (LSRII, Symphony, 3-Fortessa, 3-Fortessa X-20, 3-Attune, C6, Novocyte 3005, 2-Quanteon 4025, and Aurora). Analyzers and sorters are available for unassisted end user runs following completion of appropriate training. Additionally, ACC has a Nanosight NS300 for submicron particle characterization. Lastly, a Helios Mass Cytometer is available with core assisted operation.
As an added convenience, the ACC supports several off-line workstations where investigators can analyze their ACC-derived data. ACC software includes Flowjo, FCS Express, DiVa, Attune Software and Spectroflo.
