Short Description

The focus of this core facility is on various light and electron microscopy methods, i.a. transmitted light-, phase contrast-, fluorescence and confocal laser scanning microscopy, scanning electron microscopy ( SEM) as well as transmission electron microscopy (TEM),analytical TEM (energy filtering, EFTEM, electron energy loss spectroscopy) and electron tomography.

All these methods require elaborate sample preparations, for example chemical and/or physical sample fixation (cryo-fixation), dehydration, embedding and sectioning/ultrathin sectioning. Examples include a cryo-sectioning microtome, a sputtering device, a high-pressure freezer (Leica Empact), a cryo-substitution device (Leica AFS), a plunge freezer (KF80, Reichert), a cryo-jet device (Balzers), a freeze-etching device (Balzers), several ultramicrotomes (Reichert Ultracut, Ultracut E, Leica UC7) a cryo-ultramicrotome, trimmers (Leica EM Trim), polymerization ovens and numerous diamond knives.

For contrast enhancement, the samples can be labelled by chemical or immunological methods or also by in situ hybridization. The samples must be applied on special slides. Electron microscopic methods can be used to study biological structures from molecular to cellular and tissue level.

In light microscopy, in particular fluorescence and confocal laser scanning microscopy (CLSM), investigation of both, fixed biological samples and living cells is possible. Therefore, in the Core Facility is also equipped with safety cabinets that enable live cell imaging, toxicological evaluations and further bioanalytical investigations.

Of particular importance are light-microscopy-guided patch clamp measurements. The measuring stations allow complete electrophysiological characterization of cells up to single channel resolution. The equipment required for this purpose, such as vibration-damped tables, manipulators, perfusion systems and computer-controlled amplifiers are available.

For the further investigation of living cells and organoids in 3D, bioreactors as well as modern microfluidic analysis systems are available, thus offering the possibility of a flow living cell microscopy. The facility also has the prerequisites for producing high-quality biochips in small quantities in very fast production cycles. In particular, there is a rapid prototyping facility with a) precision 3D printer b) polymer milling machine c) hot embossing facility d) sputtering facility e) plasma cleaner f) spin coater.

This range of methods allows a variety of applications in basic and applied research, such as aging research, allergy, tumor research, stress physiology and plant biology.

Methods & Expertise for Research Infrastructure

The visualization of cellular and subcellular structures provides important information about the processes within cells and tissues. Devices from this core facility can be used to examine fixed samples that provide snapshots of cellular processes at the highest resolution, as well as to observe and digitize dynamic processes in living cells.

In addition, the devices may be used for analytical purposes, e.g. using immuno reactions to localize proteins etc. in cells and tissues (immuno-TEM) or to measure subcellular elements and to calculate elemental distribution images (analytical TEM, energy loss spectroscopy). This also includes analytical fluorescence microscopy for measuring cellular signals (Ca2 +, pH) and metabolite concentrations (glucose, ATP, NADH, etc.). FRAP = fluorescence recovery after photobleaching can be used to visualize the diffusion behavior of fluorescent substances, FRET = Förster resonance energy transfer is used to measure the distance between proteins or to detect protein interactions.

The devices are used in various cell biological and molecular biology fields, which are useful in e.g. plant biology, tumor biology, immunology research, neuro biology or stress physiology. In addition, modern fluorescence microscope systems are designed, built and developed for research.
