Flow & Mass Cytometry Facility

MISSION:

To ensure that University of Maryland investigators have access to flow cytometry and mass cytometry services for their research. A facility with dedicated operators ensures well-performing instruments and optimal results with a minimal outlay of expenses. Established in 1991, this facility has state-of-the art equipment and a highly-trained and experienced staff.


SERVICES:

Multichromatic flow cytometryFlow-Cytometry-06

Including markers for:

  • Lineage
  • Maturation
  • Activation
  • Homing
  • Intracellular cytokines
  • Cell sorting (up to 6-way)
    based on GFP and/or multichromatic staining
  • Mass Cytometry (>60 parameters)
  • Serum/supernatant cytokine levels using bead kits (e.g. BD Pharmingen CBA kit)
  • Cell cycle analysis (PI, DAPI)
  • Cell proliferation (CFSE, PCNA, BrdU and Ki67)
  • Apoptosis (Annexin V vs. PI; TUNEL; subG0/G1 peak analysis)
  • Green fluorescence protein (GFP) (eukaryotic and prokaryotic)
  • Advice with experimental design and data analysis

INSTRUMENATION:

Fluidigm Helios Mass Cytometer

Flow-Cytometry-07

Principles of Flow Cytometry

Fluidics

  • Cells in a single-cell suspension
  • Flow in a single file through

Optics

  • An illuminated volume where they
  • Scatter light and emit fluorescence
  • That is filtered, collected and

Electronics

  • Converted to digital values
  • That are stored on a computer
  • And put through software for analysis
