About
Welcome to the Brown University Flow Cytometry & Cell Sorter Facility. The purpose of this facility is to provide technical assistance to researchers at Brown and affiliated institutions by performing flow cytometry-based analysis and sorting. The facility has a 4-laser, 54-channel Cytek Aurora flow cytometer that is equipped with an automated sample loader for analysis of 96 well plates,
as well as a 3-laser, 38-channel Cytek Aurora CS cell sorter.
Related Core
The Rhode Island Hospital Stem Cells and Aging (SCA) COBRE Flow Cytometry Core’s function is to provide high quality,
cost effective, state-of-the-art flow cytometry and multiparameter cell sorting instrumentation and associated expertise
and services to all investigators in the SCA COBRE and to the general research community in Rhode Island. The Core has
a BD Sciences Influx Cell Sorter and LSRII Analyzer/Flow Cytometer. It also has a Fluidigm Helios (CyTOF) Mass
Cytometer. The Core operates the instruments, provides training for self-use and provides advise on experimental
design and data interpretation.

Services and Instruments
Instruments Available
The Cytek Aurora CS is a new and innovative technology that can analyze similar and very similar spectral emitting fluorochromes that traditional flow cytometry cannot. Instead of analyzing small chunks of fluorescence and calculating fluorescence spill over, the Cytek Aurora CS looks at the full spectrum emittance of each fluorochrome. This allows colors that would normally be unusable with each other to be run in tandem
Data Analysis & Backup
Files and experiments will occasionally pile up on the SpectroFlow software which causes the program to run at slower speeds. For this reason, every month, old experiments are deleted off the program, and saved onto the workstations hard drive, where it will be backed up at the end of the day.
Individual users are responsible for their own data analysis and backing up of data (either by transfer to USB Flashdrive or CD/DVD). There is only one PC workstation with SpectroFlow software for data analysis and/or for setting up sort profiles, which is connected to the instrument. The facility staff is available by appointment to assist in data analysis using the Flowjo software.
Protocols
Listed are several protocols that may answer some typical questions.
The Cell Sorting Guidelines are basic instructions as to how to prepare your samples for sorting. The Flow Cytometry Guidelines are basic instructions for running samples for flow analysis that do not need to be sorted. Please keep in mind that it is still very helpful to filter your samples, especially samples that come from bone marrow or are clumpy cells lines.

Flow Cytometry. This facility, located at the Biomedical Center, is directed by a PhD-level investigator and staffed by a full-time manager. The primary instrument is a Becton Dickinson FACSAria III, a 5-laser, 20-parameter instrument with analytical and sorting capabilities for up to four populations, bead-based immunoassays, and DNA cell cycle analysis. The five lasers are blue 488nm, yellow/green 561nm, red 633nm, violet 407nm and UV 375nm. A fixed-alignment cuvette flow cell provides excellent fluorescence sensitivity. The facility houses a 3-laser, 15-parameter BD FACSCelesta with blue 488nm, violet 407nm, and yellow/green 561nm lasers and equipped with a high throughput system for analysis of samples from 96 well plates. The facility also houses a four laser Cytek Aurora with blue 488nm, red 640nm, violet 405nm and UV 355nm lasers. This instrument can analyze up to 54 channel, 57 parameters and is equipped with an auto sampler loader. Consultation is available. A computer workstation with FlowJo software is provided for facility users.
Scientific reproducibility is enhanced through scientific rigor and transparency. Scientific rigor is the strict application of the scientific method to ensure unbiased and well-controlled experimental design, methodology, analysis, interpretation, and reporting of results. The Flow Cytometry and Sorting Facility is committed to supporting research excellence by adopting the following practices of scientific rigor.
- Purchase and maintain a variety of high-quality instruments from established vendors such that the best instrument is available for any given research analysis.
- The equipment is overseen by highly trained Flow Cytometry experts and well maintained under service contracts or funds budgeted for annual preventive maintenance and repairs.
- The flow cytometry and cell sorting experts are available for experimental design consults or troubleshooting.
- All Flow Cytometry and Sorting Facility users are thoroughly trained by the expert staff, one on one, and not granted access to the instruments until they are deemed to be suitably trained.
- All newly trained users are also required to use the Flow Cytometry and Cell Sorting Facility instruments during daytime hours to increase interaction with the expert staff members.
