Fluorescence Imaging


  • Inverted confocal laser-scanning microscope Carl Zeiss LSM510-META with UV and Vis Argon lasers, HeNe laser units (351, 364, 457, 488, 514, 543, and 574 nm). Multi-user device
  • Prismless TIRF (total internal reflection fluorescence) microscope with AOTF-controlled Argon laser (457, 488, and 514 nm). Cooled CCD camera, DualView emission beamsplitter for TIR-FRET imaging, and patch-clamp electrophysiology (HEKA / L&N)
  • A TIR-FRET, TIR-FLIM, TIR-FRAP microscope. Total internal reflection fluorescence excitation (TIRF) is applied in the prismless configuration (Zeiss alpha-Plan Fluar 100x/1.45) in a custom-built inverted microscope. CW-laser: AOTF-controlled multiline Argon laser (457, 488, or 514 nm); pulsed lasers: two diode laser heads with 440 and 470 nm. Probe manipulation: piezo-controlled XYZ nanopositioning system (PIMars P-563.3CD). Sensors: -70°C-cooled, back-illuminated 16-bit EMCCD camera (Andor BV-887) and two PMT detectors and time-correlated single photon counting (TCSPC; Pico-Quant) for fluorescence lifetime/FRET and anistotropy decay analyses
  • Two digital fluorescence video imaging and fluorescence resonance energy transfer (FRET) imaging setups (Agilent-TILL-Photonics / PCO) attached to Axiovert 100 inverted microscopes
  • Digital fluorescence video imaging (Agilent-TILL-Photonics / PCO) with inverted Olympus microscope
  • Various software tools for on-the-fly spectral fingerprinting, indicator calibration, FRET-analysis, FRAP and FLIM imaging
