Imaging Core Facility (ICF) provides access and training to the imaging instruments in the GSH, currently including a small animal 7T MRI (Bruker), spinning disc confocal microscope (CQ1, Yokogawa), confocal microscope (SP5, Leica), fluorescent/light microscopes (AxioImager, Zeiss), light sheet microscope (UltraMicroscope Blaze, Miltenyi), in vivo imaging system (IVIS SpectrumCT, Revvity) as well as image processing stations (CQ1 off-line image analysis and CellPathFinder, Imaris Sticher and Imaris image processing software package, Living Image software +3D module).

 

RResponsible for the training, coordination and maintenance is Dr. Tijna Alekseeva. She serves as single point of contact for all questions related to the imaging equipment, as well as advice on the experimental set up, development of new analytical pipelines and general enquiries related to imaging. At the MRI, Dr. Alekseeva is supported by Marco Lolies who is taking care of routine measurements for internal and external users. IVIS SpectrumCT is jointly maintained with Margareta Kolaric‎.

 


 

All imaging instruments are primarily available to the research groups of the Georg-Speyer-Haus. However, external research groups can apply at any time.
