Cytometry and Cell Sorting Core Facility

The aim of the Cytometry and Cell Sorting Core Facility is to provide interested scientists with access to state-of-the-art flow cytometry equipment .

  • 5 Analyzers (A3, Quanteon, LSR Fortessa (4 Laser), LSR Fortessa (5 Laser, starting on 26.5.) and Aurora starting in may)
  • 2 Sorters (AriaIIIu and AriaFusion)
  • 1 Imaging Analyzer (ImageStream)

The analyzers can be used independently after prior training and acceptance of the terms of use (also offered as a service). Both sorters, the FACS AriaIIIu and the FACS AriaFusion are operated by the facility staff.

If you require instruction, support or advice on operating the devices, please contact us.

Cell Analysis

  • FACS LSR Fortessa

    The LSR Fortessa allows, in addition to the blue, violet and red laser a yellow-green laser for better detection with the use of PE-dyes and red fluorescent proteins. Up to 17 fluorescences can be used in a sample.
    The device is equipped with the following lasers:

    • 405 nm: violet laser
    • 488nm: Blue Laser
    • 561 nm: green laser
    • 640 nm: Red Laser

  • The quanteon is equipped with 4 lasers. The special feature of this device is the determination of absolute cell counts.

    Furthermore the software provides analysis wizards for cell cycle and proliferation experiments.

    The quanteon can be used independently for multicolour experiments or as a service.

    The device is equipped with the following lasers:

    • 405 nm: violet laser
    • 488nm: blue Laser
    • 561 nm: green laser
    • 637 nm: red Laser

  • The LSR Fortessa A3 is our highend flowcytometer for getting the most information out of your sample. The device provides the 3 standard lasers plus a yellow-green and an uv-laser. It is possible to use up to 29 parameters in your sample.

    The device is equipped with the following lasers:

    • 355 nm: UV laser
    • 405 nm: Violet laser
    • 488 nm: Blue Laser
    • 561 nm: Green laser
    • 640 nm: Red Laser

  • Aurora

    For high compexity applications there is the aurora as high end flowcytometer available in the core facility. It is equipped with the 3 standard lasers plus a yellowgreen and a uv-laser. Because this cytometer is a spectral cytometer (64 fluorescence channels + 3 scatter channels) you can use fluorochromes with similar fluorescence emissions.
    The result of samples with high autofluorescence can be improved by autofluorescence extraction.

Cell Sorting

  • FACS Sortprinzip
    Lupe zum Vergrößern des Bildes

    1. Cells are harvested by a sheath flow as beads strung on a string (hydrodynamic focusing)

    2. In the laser intersection the analysis of the cells takes place.

    3. The nozzle separates the jet into individual drops and charges the drops to be sorted on.

    4. The charged drops are deflected in an electric field, and fall into the appropriate receptacle.

  • The following tables show how long a sorting operation. These are minimum hours, 20 minutes should be allocated for the setting of the device. The duration varies with the size of the cells.

    Sortdauer smaller cells

    Sortdauer for small cells (15,000 / sec, Mode:. Yield)
    Sortdauer large cells

    Sortdauer for large cells (5000 / sec, Mode:. Yield)
  • multicolor analysis

    Examples for multicolor analysis

  • The following options are possible with the FACS Aria III and FACS Aria Fusion:

    FACS 15ml tube

    1) separated into 2 populations in 15 ml tubes

    FACS tube
    FACS small reaction tube

    2) seperated into up to 4 populations in FACS-tubes or small reaction tubes

    FACS 96-well

    3) filing in microtiter plates (for example, 96-well)

  • FACS AriaIllu

    This Cytometry one or more cell populations from the suspension can be sorted out (Note: not all cells can be sorted well, sometimes the populations are very sensitive). The sorted cells can be cultivated further.
    The cell sorting on FACS AriaIIIu is handled by employees of the Core Unit. The device is equipped with the following lasers:

    • 407 nm: violet laser
    • 488nm: Blue Laser
    • 561 nm: green laser
    • 633 nm: Red Laser

  • Multi color combination
