Flow Cytometry Core

porcelliThe overall goal of the Einstein-Montefiore CFAR Flow Cytometry Core is to provide investigators with ready access to a wide array of advanced instruments for analytical flow cytometry and cell sorting in appropriate biosafety containment conditions for the analysis and isolation of specific cell populations for both clinical and basic research particularly those infected with HIV-1. 


Core Mission 

  • To maintain the necessary research infrastructure needed for flow cytometry studies, with appropriate biosafety containment safeguards.
  • To provide education, training and consultative services to assist CFAR investigators in the implementation of new and established flow cytometry techniques. 

Core Facilities 

  • Analytical Flow Cytometers for multiparametric analysis of cellular populations and nanoparticles including FACScan DxP5, FACSCalibur DxP10, Standard FACSCalibur, FACSCanto II, BD LSR II (2), Partec CyCube
  • High Speed Cell Sorters for isolation of celluar populations including MoFlo and FACSAria II
  • BSL2-enhanced biocontained High Cell Sorter for the isolation of HIV-1-infected cells using a FACSAria II housed in a Baker Bio Protect III biosafety cabinet.
  • iCys Laser Scanning Cytometer for coupling high resolution images of singe cells with quantitative fluorescence measurements.
  • Nikon Optiphot Epifluorescence Microscope for visual imaging of fluorescently-labeled cells.

Core Services 

  • High-speed cell sorting of HIV-1-infected cells or tissues infected with other pathogens using FACSAria under BSL-2-enhanced biocontainment conditions
  • Multiparameter flow cytometric analysis using MoFlo-XDP, FACSAria, FACSCanto II and FACSCalibur
  • Laser scanning cytometry of tissue sections using Compucyte iCys Laser ScanningCytometer
  • Consultation on biocontainment requirements for cell sorting experiments
  • Assistance with biohazard flow cytometry experimental design and data analysis 

Core Training Programs 

  • Regularly provide practical courses and hands-on training to CFAR investigators in the use of all analytical flow cytometers.
  • Provide training in the operation of high speed cell sorters for advanced and suitably qualified facility users under biocontainment conditions.
  • Provide consultation on design of experiments involving flow cytometry, and resources for processing and analyzing data.
  • Organize and sponsor seminars and workshops by internal and invited external experts on various aspects of flow cytometry and related topics.
