This Leica TCS SP5 confocal system is equipped for a broad range of experimental requirements. Along with a range of fixed wavelength laser lines it now has a White-Light Laser (WLL) tunable within the range x-x for precise control over fluorophore excitation. 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.
The EMU specimen preparation suite includes equipment designed for specimen preparation for microscopy, in addition to basic lab equipment. For training or access to any of these pieces of equipment, please speak to EMU staff.
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.
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.
The Zeiss LSM 780 is a high-sensitivity laser scanning confocal microscope. Unlike most standard confocal systems this instrument comes equipped with a GaAsP photodetector. This detector in addition to boasting a quantum efficiency of 45% (in comparison to 25% for standard PMTs), it can also be used as a single-point detector or as a 32-channel detector array facilitating spectral measurements. It can also be switched into a single-photon counting mode providing great signal to noise for such techniques as FCS and RICS.
