The Electron Microscopy Facility (EM) offers a variety of preparation techniques for biological samples of diverse origin. We examine the complex architecture of macromolecules, cells and tissues at nanometer resolution using state-of-the-art conventional and cryo-techniques for specimen preparation and visualization. Whether you are interested in quick sample screening or high resolution 2D or 3D imaging, we can help. Furthermore, we provide the processing of purified molecules for conventional and cryo-electron microscopy as well sample preparation for scanning electron microscopy.


    Sample Preparation Techniques

    Sample Preparation Techniques

    Depending on your question and sample we offer a variety of different preparation techniques to ensure optimal preservation of your specimen:

    • Preparation for scanning electron microscopy to study surface structures
    • Negative Staining for rapid visualization of macromolecules, proteins, viruses, organelles or bacteria.
    • Conventional chemical fixation for tissue samples and cell monolayers.
    • High pressure freezing and freeze substitution for superior cellular preservation of cells and tissues.
    • Rotary Shadowing for high contrast examination of protein complexes.
    • Freeze fracturing and etching for visualization of surfaces, membranes and the inside of membranous compartment.
    • Immersion freezing (“cryo plunge freezing”) for best possible preservation of small samples close to their native state.
    • Tokuyasu as a method for cryo-sectioning in combination with immunogold labeling.
    • Immunolabeling to locate structures of interest.
    • Ultramicrotomy: ultra-thin sectioning of resin embedded samples.

The T20 is equipped with an Eagle 4k HS camera and can be used for routine applications as well as for tomography of room temperature samples.

    It is being used for:

    • Negative staining samples

    • Tomography of room temperature samples

    With the help of the IMBA/IMP workshop, we built a new dual-axis-tomography holder for our T20 electron microscope. This holder allows to visualize the 3D structure of resin embedded samples at room temperature in higher quality and higher resolution.

    You can find it in room 4.55. and it is reservable via our EM reservation system.

    Leica EM GP

    The VBCF EM Facility also operates a Leica EM GP grid plunger. This instrument was developed by Leica Microsystems in cooperation with Günter Resch and can be used for the vitrification of suspended samples like viruses, proteins and cellular components as well as adherent cells for cryo-TEM and cryo electron tomography. The machine plunge freezes samples on grids into a secondary cryogen such as liquid ethane which then allows a direct transfer into a cryo electron microscope. Besides biological specimen, this instrument can be used for industrial emulsions.

    For optimal and reproducible results the grid plunger provides different options. One important consideration in this context is the environmental humidity which should be around 99%. For that reason the whole procedure, like pipetting the sample onto the grid and the following removal of fluid by blotting with filter paper, occurs in a humidity controlled chamber at a variable temperature between +4°C and +60°C. The blotting is carried out automatically controlled by a photosensor. Furthermore all settings, such as humidity, blotting time, grid position, LN2 level and cryogen temperature are displayed and can be adjusted on a touch-screen control panel.

    As specimen preparation with the Leica EM GP has been proven very successful so far, this instrument has become the standard for preparation of vitrified specimen for cryo electron microscopy in our lab.

    Hitachi TM-1000

    Hitachi Tabletop Scanning Electron Microscope TM-1000

    This is a imaging platform for surface visualization at higher resolution and deeper focus depth than achievable by light microscopy. The image is generated with back-scattered electrons induced by an electron beam of 15 keV.

    Sample preparation is straightforward since it does not require coating with a conductive layer. The biological material might be frozen in liquid nitrogen. Alternatively, it might be chemically fixed and critical point-dried.

    Susanne Reier

    Günter Resch was responsible for establishing the electron microscopy facility at IMP/IMBA and was also the head of this Facility from 2006 to 2011. Later, he led the transfer of the facility into the CSF, where he was facility head until February 2014. He is an expert in cryo-electron microscopy, electron tomography, negative staining and rotary shadowing. Amongst other things, Günter was in charge of the FEI Tecnai Polara cryo-TEM and he was working on the development of new technologies. He has now moved on to his own company Nexperion, offering software, training, and consulting services for electron microscopy.
