ACTRI-Affiliated Flow Cytometry Core Facility

Due to the COVID-related closure of the ACTRI, the Flow Cytometry Core Facility is currently closed and this service request is temporarily disabled to prevent use.

The Flow Cytometry Core facility is now open at UC San Diego Altman Clinical and Translational Research Institute (ACTRI). This facility provides a high-end flow cytometer to identify, analyze and quantify cells in several sample types. It is equipped with a ZE5 Cell Analyzer from Bio-Rad, which is a benchtop system used for analysis (not sorting). The ZE5 offers great flexibility in sample handling with the ability to use several sample formats, such as single tubes, tube racks (up to 40 tubes/rack), 96-well plates (U- and V-bottom) and 384-well plates. The built-in sample loader on the ZE5 minimizes hands-on time for sample loading, allows for sample mixing with adjustable orbital vortex shaker and provides active temperature regulation of samples. The ZE5 also has a new and innovative software allowing for easy experiment design and set-up.

The ZE5 in the ACTRI flow core has four lasers (violet (407nm), blue (488nm), yellow-green (561nm) and red (640nm), enabling detection of up to 15 fluorometric parameters, including SSC. The ZE5 is equipped with a ZE5-Eye monitor to ensure that researchers have the right filters in place for their experiments, avoiding errors associated with misplaced filters and loss of detection.


Computer Workstation:
We have a new computer workstation for your use (through recharge) that includes a computer and the software Flowjo, which is used to analyse flow cytometry data.

Presently, the facility is only offering self-operated use. Prior to self-operating the equipment, researchers must complete a two-hour training session. Assisted use may be available under certain circumstances and after discussion with the core director and manager.

For more information or to schedule appointments for initial training and access to the ZE5, please contact the flow cytometry core manager.

If you are visiting our facility from another part of the UC San Diego campus or are a non-UC user, we will reimburse your parking by subtracting from the recharge time you spend using our core. You must provide a parking receipt for your core time use.
