Microscopy techniques

Advanced Light Microscopy & Image Analysis  - Technology Platform offers several high end state-of-art microscope setups for a wide range of imaging techniques and applications.

Many of the setups are equipped for live imaging.

 Confocal and Two-Photon Microscopy  
 

Our confocal microscopes are equipped with multiple laser lines, various objectives and spectral detectors (PMTs or high sensitivity detectors). Two-photon excitation is possible for thick samples. Observation of subcellular structures can be done with the high-resolution Airy scan detector. A dedicated FLIM microscope can be used to study intracellular protein-protein interactions.

More information is available for internal users here.

Two-Photon Microscopy for in vivo deep tissue imaging
 

Deep tissue and organ imaging is possible due to the high penetration depth of the infrared radiation in Two-Photon microscopy. Our dedicated setup is completed with equipment for maintaining conditions for long-term live imaging. Large area imaging is possible for cleared or un-cleared tissue samples.

More information is available for internal users here.

Instrument

Some Applications

  • Two-photon flourescence imaging for non-transparent tissues labelled with flourescent proteins, selected flourophores or quantum dots using up to three different excitation wavelengths and six detection channels simultaneously and possibilities for spectral unmixing
  • in-vivo flourescence imaging of cells expressing flourescent proteins and/or of blood vessels labelled with flourescent dextranes or quantum dots
  • SHG (second harmonic generation) of collagen fibres
  • Functional imaging of intracellular signals such as Ca2+ activation

Superresolution & TIRF Microscopy
 

Breaking the resolution limit is possible using several microscopy techniques. We offer wide field TIRF microscopy for studying dynamic membrane processes in live cells and possible applications to localisation microscopy (e.g. PALM). Our STED microscope can be used for both fixed and live samples as well as for the RESOLFT technique.

Wide field microscopy & laser microdissection
 

Laser microdissection is applied for specific isolation of individual cells or larger areas of a tissue sample, which will undergo further molecular analysis, i.e. contamination-free molecular analysis of DNA, RNA and proteins.
