Flow Cytometry Core

The Flow Cytometry Core is a state-of-the-art facility to accommodate a range of cell sorting and analysis needs. This Core supports a wide variety of applications, including high speed cell sorting, 30-color cell analysis, cytokine analysis by multiplex bead arrays (Luminex), imaging flow cytometry (Amnis Image-Stream), phosphoprotein analysis, cell cycle and ploidy analysis, protocol standardization / methods development for high dimensional flow cytometric assays for longitudinal studies. Core also provides training for end users for instrument operation and assay specific training on one-on-one manner.

    5. Training and Consultation
      1. One-on-one personal training for instrument operation, methods development, and troubleshooting.
      2. Teaching of best flow cytometry practices for data generation and analysis.
      3. Perform extended data analyses as needed.
  2. 24 x 7 Self-service Facility
    1. 24 x 7 operation at Bldg. 10 8th floor Corridor C (8C104), for all analyzers and at CRC 3rd floor (Rooms 3-5217, 3-5225, and 3-5209) for all analyzers and the Melody cell sorter by trained users.
