STED supreresolution nanoscopy

STED is the abbreviation of STimulated Emission Depletion and is a technique applied to microscopy, providing better resolution than traditional confocal microscopy. The STED resolution improvements come from a reduction of the physical dimensions in the focal spot from where the fluorescence can be emitted. This is achieved by introducing a depletion donut mask overlapping the diffraction-limited spot in the focus plane. By increasing the laser power of the depletion laser the donut gets bigger and consequently the spot gets smaller. This is achieved in all three dimensions.

Our new Leica SP8 STED 3X microscope is equipped with a pulsed white-light laser that works in conjunction with an AOBS (acoustic optical beam splitter) providing any wavelengths between 470 and 670nm. The STED is provided by 3 powerful depletion lasers with wavelength 592, 660 and 775nm covering fluorophores of most of the visual spectra. It is fitted with sensitive hybrid detectors (HyDs) with time gating of the fluorescence signals and a 3D vortex for adjusting the ratio between the lateral and axial resolution. The microscope also has a high speed resonant scanner, a fast piezo z-drive and an incubator for live cell imaging.


STED superresolution microscope: Leica SP8 STED 3X

Location: Kunnskapssenter 3rd. floor, room 423.03.031 Confocal Imaging lab

Confocal laser scanning microscope equipped with a gated 3D STimulated Emission Depletion (STED) module for super resolution.

The programmable AOBS (acousto-optical beam splitter) provides up to 8 simultaneous excitation lines. The tuneable and pulsed white light laser (WLL) together with the spectral detection system enables freely tunable excitation from 470-670nm (1 nm steps) along with freely adjustable emission detection bands. Additional features include Lightgate functionality, which allows for  temporal gating of the excitation light and Lambda Square that enables spectral mapping of  excitation and emission information. The system has 4 internal detectors: 2 HyD (high sensitivity,  hybrid GaAsP photon counting detectors) and 2 PMTs; high speed resonant scanner (8 KHz) and  SuperZ galvo stage for fast lateral and axial acquisition; Adaptive Focus Control (AFC); a Ludin  incubation chamber (temperature controlled, active CO2 gas regulator) as well as Huygens  deconvolution software for 3D STED data sets.

TIRF microscopy

Total Internal Reflection Fluorescence (TIRF) microscopy is the ideal tool to study cellular processes in the plasma membrane area. Because only a thin layer of the cell above the coverglass is illuminated, the rest of the cell is not disturbed. This fact results in a good signal to noise level, low bleaching, less stress to the cell and enables long time live imaging.

Our new Zeiss TIRF 3 is a laser based microscope that also works in epi-fluorescence mode. The system has 4 high powered lasers for rapid live cell photo bleaching experiments and two sensitive EMCCD cameras with a chromatic splitter for acquiring two fluorescent probes simultaneously. This microscope is equipped with excellent optics for enhanced resolution in TIRF mode and is also fitted with an incubator.
