Light microscopy and sample preparation
Our light microscopy capabilities provide a range of imaging solutions ideal for imaging biological samples, such as live or fixed cells and tissue sections. We provide support and advice spanning custom sample preparation (including sample preparation equipment, validated reagents and consumables) through to sophisticated 3D image data analysis.
Why use our light microscopy equipment?
- Light microscopy is used to visualise and analyse morphology, structure and molecular interactions in living cells as well as fixed tissue or inorganic substrates. It is commonly used in all disciplines of biological and biomedical research, including cancer research, neuroscience, immunology, microbiology, marine biology and plant science.
- Light microscopy is regularly used for simultaneous multiplex analyses of a variety of molecular species by virtue of combining detection of various colourimetric or fluorescent reagents across the visible to far-red spectrum. This enables inter-relationships of up to five different molecular species to be readily assessed in tandem within the same sample.
- Confocal microscopes facilitate fluorescence imaging with optical sectioning, thus removing unfocused light giving clearer images and enabling acquisition of 3D data sets. Sophisticated 3D image analysis software can provide detailed morphology and structural inter-relationship data.
- The lateral resolution of optical microscopy is no longer constrained to diffraction limits of ~200-250 nm. Our Zeiss LSM 880 Confocal Microscope with Fast Airyscan makes routine and live cell imaging with a lateral resolution to 120 nm simple to achieve and improves axial resolution 1.7x. Analysis of proximity between two different molecular species within 10-20 nm is also possible by techniques such as Fluorescence Ligation Proximity Assay and Fluorescence Resonance Energy Transfer (FRET), thus many molecular interactions can be visualised in live cells in real-time. Analysis of diffusion, velocity and stoichiometry can also be quantified in live cell culture systems via a range of mathematical image data analyses.
Our light microscopy equipment
Zeiss LSM 880 Fast Airyscan Confocal Microscope
The Zeiss LSM880 Fast Airyscan laser scanning microscope is capable of near-super resolution imaging of commonly used fluorescence dyes on live cells—as well as fixed samples—without the need for special sample preparation techniques or software deconvolution. This inverted microscope is equipped with environmental control and auto-refocusing for short and long term live cell imaging and fast spectral data acquisition with on-the-fly spectral unmixing, enabling FRET and FRAP to be assessed in real-time and fluorophores/autofluorescence with overlapping emission spectra to be discerned. This instrument features 405, 548, 488, 514, 561 and 633 nm laser lines; very high sensitivity and signal to noise ratios; a range of dry, water-immersion and oil-immersion lenses and versatility of imaging speeds; a high speed CMOS camera; and PMT, GaASP and transmitted light detectors with DIC optics, set on an antivibration air-table. It will be available from mid-2019.

Leica SP5 Confocal Microscope
The Leica SP5 laser scanning confocal microscope features tunable emission range detection which can be adjusted to any bandwidth in the visible to near far-red spectra as well as Fluorescence Correlation Spectroscopy (FCS) capability. It is equipped with 405, 458, 488, 496, 514, 561 and 633 nm lasers lines, five PMT detectors, a transmitted light detector with DIC optics, and two single photon sensitive filtercube-based detectors (avalanche photo-diode detectors) and a resonant scanner (8kHz) for high sensitivity or high speed scanning, respectively. This inverted microscope is equipped with a range of water, glycerol and oil immersion lenses and is suitable for fixed sample imaging and short term live cell imaging with temperature (but not CO2 or humidity) control. A variety of high-end techniques such as FRET-AB, FRET-SE, FRAP are made easier with software wizards.
