Siteman Flow Cytometry (SFC)


Bill Eades

The Siteman Flow Cytometry Core offers services for flow cytometry-based cell analysis, cell sorting and flow cytometry instruction. The instrumentation includes five benchtop analyzers and four cell sorters.


The analysis section of the core offers self-service on five digital FACScans, updated to three lasers and either eight or 10 colors by Cytek Development. FACScan 2 offers the ability to aspirate directly from 96-well microtiter plates. Optics are fixed, and specifications/example fluorophores are described here.

Operator training for flow cytometry is required for self-service and available by individual three-hour appointment. FlowJo Collectors Edition is used for acquisition.

Eight computer workstations are available in the core for post-acquisition data analysis at no charge. They are offered on a first-come, first-served basis and include FlowJo, Kaluza, Summit and WinList analysis suites. These applications are meant to be self-taught, but training is available by appointment.


Cell sorting is performed by a highly trained staff that is keenly aware of the physical science surrounding electrostatic sorting. Over 50 years of collective experience from varied specialties converge and include clinical process, sample preparation, and instrumentation design and support. All cell sorters are configured for flexibility. Given proper notice, the staff can set up for esoteric laser wavelengths and emission filter combinations, as well as up to four-way subset sorting and sorting into well plates. Details about specific cell sorters can be found here.

As always, any pathogenic potential of samples must be disclosed, and an IBC protocol for your lab must be produced before any analysis acquisition or sorting will be scheduled.

NIH PUBLIC ACCESS POLICY: As of April 7, 2008, the NIH requires investigators with a publication using Siteman (or other NIH-funded) shared resources to submit (or have submitted for them) their final, peer reviewed manuscripts to PubMed Central(PMC) upon acceptance of publication, to be made publicly available within 12 months of publication. Many journals automatically submit these for authors, but Washington University also has assistance available through the Becker Medical Library. Please see or for more information.

PUBLICATION ACKNOWLEDGEMENT: If research supported by the Siteman Flow Cytometry results in publication, please acknowledge this support by including the following in your publication(s):
