Flow Cytometry Facility

Flow Cytometry Facility

The 1,200-square foot Flow Cytometry Facility is located in the Eckstein Medical Research Building (EMRB). The Facility has one magnetic-based and ten laser-based instruments whose major purpose is the identification and isolation of various cell populations. The laser-based instruments accomplish this by the use of antibodies to which various colors or dyes have been attached and are directed at molecules known to exist on the cell surface or in the cytoplasm. By using several colors attached to different antibodies, one can identify and purify cells that express any given configuration of various molecules.

Flow Data

In addition to identification and isolation of various cell populations using antibodies, flow cytometry can analyze:

  • Cell proliferation response to drugs or treatments, such as those used in chemotherapy
  • Cell physiological properties, such as calcium flux and pH
  • DNA content and integrity
  • Transfection markers such as GFP and mCherry
  • Quantification of cytokines, gene expression, micro RNA

The Facility provides scientific and technical personnel who are available for consultation in designing experimental protocols and training in the use of bench-top instruments and software programs for the interpretation and analysis of data. Cell preparation protocols and publication quality output are available upon request.

Offline data analysis using FlowJoTM, DiVaTM, and ModFITTM can be done through the Facility's system of networked computers. Investigators can perform analysis at their laboratories or offices by accessing data through the Facility's dedicated file server. Data are archived on a separate server and stored for at least ten years.

A secure, web-based reservation system allows investigators to schedule instrument time. The Facility is staffed M-F, 8am to 6pm and is available 24/7 following training.
