Microscopy Facility

Within the School of Biological and Behavioural Sciences, we have a number of microscopes available to support research, providing students and academic staff with access to high quality microscopy systems.

DeltaVision Ultra High Resolution Microscopes

Deltavision Elite

Deltavision Core

Our DeltaVision Ultra High Resolution machines allow high-resolution epi-flourescent imaging in both fixed cell and live cell settings. We have one DeltaVision Elite microscope and one DeltaVision Core microscope which allows cutting-edge imaging settings. 

The machines are equipped with both air and oil objectives and allow FRET and FRAP measurements.

In order to access the DeltaVision Elite microscope, please contact Dr Fabrice Caudron at f.caudron@qmul.ac.uk

If you would like to use the DeltaVision Core microscope, please contact Professor Viji Draviam at v.draviam@qmul.ac.uk

SBBS Confocal Microscope Facility 

Leica STELLARIS 8 Confocal MicroscopeImage: Leica STELLARIS 8 Confocal Microscope

The Facility is located in the Joseph Priestley Building and it houses a Leica STELLARIS 8 confocal microscope with FLIM and DLS modalities. The SBBS Confocal Microscope Facility was established in 2009 and in 2023 joint funding from BBSRC (BB/W019698/1) and QMUL enabled upgrading of the confocal microscope with a new system. 

STELLARIS 8 FALCON is a fully integrated solution for Fluorescence Lifetime Imaging (FLIM) that enables video-rate lifetime imaging for rapid kinetic studies in live cells. FLIM measures the fluorescence decay lifetime of fluorophores on picosecond-to-nanosecond timescales. It is ideal for quantitative Förster Resonance Energy Transfer (FRET) measurements of protein-protein interactions, and can also help distinguish between different fluorophores with similar emission spectra. Software wizards for FRAP and FRET are available.

STELLARIS 8 Digital LightSheet (DLS) unites confocal and light sheet microscopy in one system. 

TauSense uses fluorescence lifetime to provide a measure of contrast (TauContrast) that is independent from fluorescent intensity. The TauSense imaging tools include TauContrast, TauGating which uses differences in average photon arrival time to remove unwanted background, and TauSeparation for multiplexing using differences in fluorescence lifetime. 

The LIGHTNING module allows for super-resolution microscopy.

Excitation is provided by a selection of diode and solid-state lasers and Leica’s supercontinuum White Light Laser (WLL), tuneable from 440-760nm and combined with an Acousto-Optical Beam Splitter (AOBS®) allowing up to 8 simultaneous laser lines.

Four HyD S and one HyD X power detectors provide high sensitivity across a broad spectral range. The HyD X in Position 3 is the most sensitive, and is specialised for FLIM and Fluorescence Correlation Spectroscopy.

An OKO Lab Microscope cage incubator maintains samples at stable temperatures from 23 to 450C. The inverted configuration of the Leica DMI 8 microscope enables imaging of samples immersed in open wells. 

Lasers available:

  • Diode laser 405
  • Diode laser 638 nm
  • Solid state laser 488nm
  • DP solid state laser 561 nm
  • White light laser: 440nm-790 nm

Objectives available:

  • HC PL FLUOTAR 2.5x/0.07 DRY
  • HC PL APO CS2 10x /0.40 DRY
  • HC PL APO CS2 20x /0.75 DRY
  • HC PL APO CS2 40x/1.30 OIL
  • HC PL APO CS2 63x/1.40 OIL
  • HC PL APO CS   63x/1.30 GLYCEROL

Image Processing Software

Facility users have access to Dell computer with Imaris (version 10.0) image processing and analysing software; the package includes ImarisCore, ImarisColoc and MeasurementPro.

Contact

Training in use of the Leica and Confocal microscopes, including the completion of an induction session provided by the facility manager, is required before new users can work independently in the facility. Please contact Michaela Egertova on 0207 8826664 or email m.egertova@qmul.ac.uk to arrange.
