This microscope combines a total internal fluorescence (TIRF) and highly inclined and laminated optical sheet (HiLo: https://www.nature.com/articles/nmeth1171) modalities in one instrument. The TIRF modality allows user to image molecules at surface of cells and apply super- resolution imaging techniques such as PALM and STORM. HiLo modality offers the possibility of exciting a thin inclined plane within cells or thin layer of cells within few micrometers of a live animal tissue. Automatized variability of angle of HiLo emergence and camera imaging allows for fast sectioning of sample. The system is also supplemented with NIDAQ board and control with external trigger, which combined with the versatile illumination sequence option makes this ideal microscope for complex experiments involving the correct timing of imaging following an external stimulus of cells or animal. Definite focus is perfectly controlled using Nikon PFS system making it ideal for long term live cell or animal imaging.
The Leica TCS SP8 DLS (Digital LightSheet) is an inverted laser scanning microscope capable to be used for confocal imaging and light sheet imaging. This microscope is able to image multi-colour, live, fixed or aqueous-based cleared specimens utilising a combinations of 405, 458, 488, 514, 561 and 635 nm excitation lasers through the employment of the AOBS with spectral high quantum efficiency detectors. The advantage of the two combined features (confocal/Lightsheet) on a single equipment allow to perform, with the confocal module, local photo activation or photo bleaching where the resulting dynamics can be capture via lightsheet imaging on thick sample (up to 2 mm thick and 1 cm long).

Fitted with Hybrid Dectors (HyD) for enhanced sensitivity, and interchangeable Galvano and resonant scanners, this system is suitable for applications requiring both speed and/or improved signal-to-noise. Its Gated-STED module also enables colleciton of super-resolution images allowing investigators to distinguish objects and structures beyond the conventional resolution limit of light.
Leica TCS SP5 equipped with a Spectra-Physics Mai Tai Ti:Sapphire laser is an inverted confocal laser scanning microscope. It is designed for high-resolution fluorescence and transmitted light imaging with single or multi-photon excitation, in 2D, 3D or 4D with live or fixed cells. It can also be used for Fluorescence Recovery After Photo bleaching (FRAP), pulsed Stimulated Emission Depletion (pulsed STED) and Fluorescence Correlation Spectroscopy (FCS). In combination with the Picoquant Microtime200, it can be used for Fluorescence Correlation Spectroscopy (FCS) coupled to Fluorescence Lifetime Imaging (FLIM).
The Zetasizer Nano ZS is a high performance two angle particle and molecular size analyser for the enhanced detection of aggregates and measurement of small or dilute samples, and samples at very low or high concentration using dynamic light scattering with ‘NIBS’ optics. The ZSP also incorporates a zeta potential analyzer that uses electrophoretic light scattering for particles, molecules and surfaces, and a molecular weight analyzer using static light scattering.
Lighsheet microscopy is a fluorescence-based imaging technique that is growing in popularity. It outperforms other techniques in its ability to rapidly capture large optically sectioned three dimensional datasets, whilst keeping photo-toxicity and bleaching to a minimum. It therefore lends itself well to imaging samples larger than those typically attempted by conventional fluorescence microscopy such as tissues, whole organs and even embryo development.
The FV1200 is a filter based upright confocal system. A workhorse of our confocal systems it is well equipped for standard fixed samples where high resolution and sensitivity are required for localization based studies. Additionally as one of the few upright confocal systems within the BMIF it provides a means for visualizing water submerged opaque samples.
The Zeiss LSM 880 is an inverted laser scanning confocal microscope equipped with high quantum efficiency GaAsP detector and 2 multialkali PMTs, which can be used as single point detectors or combined for 34 channel spectral imaging. In addition, the Airyscan module can deliver images with 1.7 x improved resolution (140nm axially, 400 nm laterally) and 4-8 x greater signal-to-noise ratio, at the highest speed of any linear scanning confocal system. BiG.2 Type A (2x GaAsP detectors) non-descanned detectors for the multi-photon laser can be used for imaging thick specimens, with deeper penetration and decreased phototoxicity compared to single photon lasers. The Picoquant system utilises the multi-photon laser to perform Fluorescence Lifetime Imaging (FLIM), Fluorescence Correlation Spectroscopy (FCS), Forster Resonance Energy Transfer (FRET). The Zeiss 880 is also equipped with polarisers for anisotropy measurements.
Leica RM2135 rotary microtome is used to cut very thin cross-sections of specimens (usually 4 µm) for routine and research histology studies in the fields of biology and medicine. This instrument is designed for cutting soft and harder paraffin embedded specimens, as long as they are suitable for being cut manually. The sectioning thickness setting range can be from 1 µm to 60 µm. High quality paraffin sections could be used for varying staining, such as Haematoxylin and Eosin stain (H&E), immunohistochemistry (IHC), Immunofluorescent staining (IF) and In situ hybridization (ISH).
The Nikon Eclipse TiE is ideally suited for live cell imaging studies. With one of the best focus stabilisation devices on the market the Perfect Focus System (PFS) ensures that the focus you set at the start of the experiment will be maintained throughout its entirety. They system is fitted with several phase contrast objects making it suitable for imaging cells through a range of materials including plastic, as well as 3 high NA DIC objects for achieving astounding detail if imaging through glass.
The Microtime200, manufactured by the German-based PicoQuant GmbH, is generally used in conjunction with the TCS SP5 microscope. By using the lasers from the TCS SP5, the Microtime200 is capable of measuring how fast proteins move within the cell (diffusion) and protein to protein interactions.
This microscope has a unique design, allowing for a great deal of customization of the sample space and experimental design. The system is designed for up to four-color total internal fluorescence (TIRF), photoactivation (PA), fluorescence resonance energy transfer (FRET), widefield correlation spectroscopy (WCS), spatio-temporal image correlation spectroscopy (STICS), and fluorescence recovery after photobleaching (FRAP) experiments, all at high frame rates. Single-molecule measurements can be enhanced with a pair of single-photon avalanche photodiodes (APDs) and a pulse correlator for fluorescence correlation spectroscopy (FCS) and fluorescence cross-correlation spectroscopy (FCCS) experiments. An environmental chamber allows for these techniques to be extended to live cell samples.
