Thermo Scientific CryoStar NX70 is a high-performance cryostat designed to prepare tissue
sections of frozen samples in medical and research laboratories. Specimen temperature control range is from -50oC to +10oC and blade temperature control range is from -35oC to -5oC. Section thickness can be ranged from 0.5 µm to 500 µm. Fresh or fixed frozen specimens, embedded in OCT, are suitable for cryostat sectioning. Frozen sections could be used for varying staining, such as histology stains, Immunohistochemistry (IFC) and Immunofluorescence (IF) stains.
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.
The VisualSonics Vevo2100 uses the new solid-state transducers which offer higher resolution at multiple focal depths. The system offers superior resolution down to 30μm, a wide range of frequencies (13-56 MHz) and a large field of view. Importantly, the Vevo2100 offers a comprehensive imaging and processing packing.
The zeiss Spinning Disk/TIRF system is a custom built instrument. Built upon an Axio Observer X.1 body it is equipped with a Yokogawa Spinning disk CSU-X1 module providing confocal imaging at rapid frame rates captured on an EM CCD camera (Quant EM) ideally suited for low light imaging. Attached to a different microscope port is a highly sensitive high frame rate sCMOS camera (Orca Flash 4) which can be used for standard epifluorescence, rapid ratiometric imaging utilising a fast excitation switching light source (Lambda DG4) or acquire fluorescence images using TIRF illumination.
The Zeiss Elyra Superresolution Microscope is a developmental superresolution microscope with capabilities to push imaging past the classic diffraction limit. Typically visible light microscopes cannot achieve spatial resolution of greater than 200-250 nanometers. This system has two different imaging modalities to push this limit as low as 20 nanometers.
