About Us 

The Flow Cytometry Shared Resource provides researchers with ready access to the necessary expertise and state-of-the-art instrumentation they need to explore a wide range of research problems with flow cytometry.

We focus on addressing the needs of seasoned flow cytometry users, as well as those just discovering the capabilities of flow cytometry technology. We provide monthly training for the instruments for new users. The directors are also available to consult on experimental design and data analysis.

Areas of Focus 

The typical experiments handled by the Flow Cytometry Shared Resource Facility are designed to do analysis or to sort based on up to 9 fluorescent parameters. Some representative examples of analysis experiments include the:

  • Measurement of DNA and RNA content for cell cycle analysis
  • Cell cycle specific nuclear and cytoplasmic proteins
  • Apoptosis markers
  • Substituted deoxyuridine incorporation
  • Stem cell side populations
  • Reactive oxygen species
  • Cell surface markers using labeled antibodies or substrates
  • Cell viability
  • Intracellular ion concentration or pH
  • Membrane potential

Cell lysates can also be analyzed with bead substrate based immunoassays. Some representative examples of sorting experiments include:

  • Purification of cells transfected with fluorescent protein tagged DNA inserts
  • Isolation of cell populations expressing specific intracellular or membrane metabolic products.

Use of the Instruments 

The institutional instruments available as part of the Flow Cytometry Shared Resource include:

  • Located at the Biotech Place
    • BD FACS Aria cell sorter (3 lasers and 11 parameters)
      • Sorting tips available:  70 micron, 100 micron & 130 micron.
      • Capable of single cell sorting into 24 and 96 well plates
      • Instrument is fitted with a special flow cell to provide better precision for measuring DNA content and side-populations
    • BD FACS Canto II analyzer (3 lasers and 10 parameters)*
    • BD FACS Calibur analyzers (2 lasers and 6 parameters)*
  • Located at Hanes Building, 4th floor, Room 4063
    • BD Accuri C6 analyzer (2 lasers and 6 parameters)*
    • In addition to the software available with each flow cytometer, FCS Express flow cytometer analysis software is available to analyze the multiparameter data to identify and characterize cell subpopulations. DNA histogram analysis software programs (ModFit and MultiCycle) are also available to address the needs of researchers requiring advanced cell cycle analysis.

* Instruments are available to use 24 hours, 7 days a week. Users must seek the appropriate instruction to be approved instrument operators. See below.

Reservations to Use the Equipment 

Investigators reserve time on the FACS Calibur, BD Accuri and FACS Canto via a Web-based public calendar that is accessible to all trained institutional users.

Reservations for sorting time on the FACS Aria are made by direct communication with Dr. James Wood or Beth Holbrook, as these individuals are responsible for performing the sorts. (See contact information below). Cost for instrument utilization is as follows: 

  • FACS_Calibur:  $55/hour
  • BD Accuri C6:  $60/hour
  • FACS_Canto:  $60/hour
  • FACS Aria: cell sorting $85/hour, plus a $40 set-up fee

Cancer Center members performing cancer related studies receive a 30 percent subsidy for cancer-related projects.​

Consultative Services

The directors provide consultative services at no charge to the investigator for discussions regarding experiment design, execution or interpretation. In many cases, this saves the investigator time and resources by preventing mistakes in the initial experimental design that may not be obvious to less experienced users. Investigators also have access to the wide network of pre-eminent flow cytometry users from academia and industry via personal introductions by Dr. Wood, who has extensive connections in this field.


Hands-on training is provided for individuals who would like the ability to acquire their data on the FACS Calibur, BD Accuri C6 or FACS Canto. Dr. Martha Alexander-Miller should be contacted directly to schedule for the one of the monthly training sessions for the FACS Calibur. The training for the BD Accuri is coordinated by Dr. James Woor. The training for the FACS Canto is coordinated by Dr. Martha Alexander-Miller. (See contact information below)
