Flow Cytometry Core Facility

Flow cytometry core facility has reopened.

Core Manager (primary contacts): Myungja Ro

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.

Presently, the facility is only offering self-operated use. Prior to self-operating the equipment, researchers must complete a two-hour training session (at least 2 hours, $200/ hour). Assisted use may be available under certain circumstances and after discussion with the core manager.

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