"The Deltavision CoreDV Widefield Deconvolution System is a high resolution widefield microscope for acquiring images of live or fixed samples. The system is built on an Olympus IX71 inverted microscope and features an LED transmitted light source for differential interference contrast and a 7-color solid state illumination unit for exciting fluorophores across the visible spectrum. Polychroic beam splitters, optimized for imaging with Blue-Green-Red-FarRed fluorophore combinations in fixed cells or CFP/YFP and GFP/RFP combinations of expressed proteins in living cells, are combined with emission switching through fast filter wheels. Images are captured on a Nikon CoolPix HQ cooled CCD camera. The motorized stage is controlled by XYZ nanomotors for accurate z-stack and point-visiting functions."
The IncuCyte ZOOM is an imaging device that sits in a tissue culture incubator and takes time-lapse images of cells in phase and red and green fluorescence. The device is particularly suited for monitoring cell growth and migration. A variety of culture vessels are accommodated in this device. Conveniently, captured image data is accessible from any computer on OHSU’s intranet.
"This setup is custom-built around a Yokogawa W1 spinning disk confocal head mounted on a Nikon Ti inverted microscope with PFS attachment for continuous Z-drift compensation during live-cell imaging. This is a four color system (405nm, 488nm, 561nm, and 631nm). X,Y,Z axes are motorized to allow for position marking and revisiting during long-term timelapse recordings. A Piezo-driven Z axis top plate allows for fast Z stack acquisition with all available objectives. Objectives range from low magnification dry objectives to high NA oil immersion objectives. The system has full environmental control for live-cell imaging."
"This laser scanning confocal is mounted on a fully motorized BX-71 upright microscope base. The stage is motorized in X,Y to mark positions for revisiting or stitching neighboring field-of-views into a single image. The strength of this system is its upright stand configuration that allows samples to be imaged from the top using dipping objectives."
The Zeiss Apotome setup is a wide-field microscope setup with a choice of a black-and-white or a color CCD camera for fluorescence- or colorimetric-based immunohistological detection. The Apotome device captures optically sectioned images from thin tissue sections more efficiently than a laser-scanning confocal microscope. The setup is equipped with a motorized x,y stage that can be used to stitch images across a piece of tissue larger than the field-of-view captured in a single image.
The Zeiss Elyra PS.1 setup implements two different super-resolution technologies. It is capable of structured illumination microscopy, which can improve resolution 2-fold in each dimension, or 8-fold in volume. This technology uses labeling procedures commonly used for laser-scanning confocal microscopy and direct comparison of confocal and super-resolution imaging is possible on the combination setup. The system is also capable of single-molecule localization microscopy, a specialized super-resolution method that achieves almost 10-fold improvement in resolution in x and y.
"The Zeiss LSM780 is mounted on a fully motorized AxioObserver Z1 inverted microscope stand. The stage is motorized in X,Y to mark positions or acquire images of areas larger than the field of view through tiling of individual image stacks. An optional stage-top incubator is available to control temperature and atmosphere and a Definite Focus attachment compensates for slightest Z-drifts during live-cell timelapse imaging."
"This protocol is provided for use with the pDendra2 Vectors which encode a green-to-red photoswitchable fluorescent protein derived from the octocoral Dendronephthya sp. Dendra2 switches irreversibly from green to red when exposed to intense 405 or 488 nm light."
