Major Equipment for Integrated Cellular Imaging Core (ICI) Users
INTEGRATED CELLULAR IMAGING CORE (ICI)
The Integrated Cellular Imaging Core (ICI), one of the Emory Integrated Core Facilities (EICF), provides state-of-the-art light microscopy and image analysis platforms. ICI offers confocal, spinning disk confocal and live cell imaging, multi-photon animal and tissue imaging, widefield with deconvolution, super resolution, light sheet and image analysis. To effectively implement these technologies, ICI provides consultations, expert training, and support for all our systems. We assist our users from bench to publication, starting with designing experiments tailored to the specific microscope, through training and data acquisition, to data analysis and interpretation.
Leica SP8 (Winship): The Leica SP8 confocal laser scanning unit, attached to the latest Leica inverted DMi8 body, comprises an infinitely flexible prism based spectral detector system and multiple excitation laser lines (405, 488, 514, 561 and 633nm) for a vast variety of experimental and labeling options. Four channel detection, via two PMTs and two extremely sensitive Leica HyD detectors (GaAsP based), together with 8 kHz resonant scanning provides high speed imaging. A transmitted light detector allows for simultaneous laser scanned DIC or phase imaging. A stage and objective warmer facilitates numerous live cell imaging approaches such as FRET, FRAP, and photoconversion. High speed automated tiling/stitching and multipoint location acquisitions are also possible in combination with the above.
Olympus FV1000 (HSRB): This FV1000 confocal laser scanning microscope is mounted on an inverted Olympus IX81 microscope with a motorized x-y-z stage. It has a three channel PMT detection system with grating based spectral detectors on channels 1 and 2 (allowing for spectral unmixing). In addition, a transmitted light detector provides laser scanned DIC for label free imaging. These coupled with 6 excitation laser lines (405, 458, 488, 515, 559, and 635nm) facilitate highly flexible imaging combinations.
Olympus FV1000 (Whitehead): This FV1000 laser scanning microscope is identical to the HSRB FV above, except it’s filter based detection on all channels and a different combination of excitation laser lines (405, 488, 515, 543, 635). Having near identical systems in two locations provides easy secondary options without additional trainings during maintenance and repairs.
Live cell confocal imaging:
Nikon A1R HD25 (Whitehead): This live cell confocal laser scanning microscope is optimized for imaging cellular dynamics at high speed and a large view of view (25mm). A hybrid dual scanning confocal system with both galvanometric and resonant scanners, together with a piezo z controller, can acquire 1024x1024 images at 15 fps, 512x512 images at 30 fps, or with a reduced size up to 720 fps. A stage top environmental chamber at 37° C and 5% CO2 required for live cell imaging, coupled with a Perfect Focus system, provides extremely stable long-term imaging without drift. Flexible laser scanning control for photokinetics experiments can be conducted in multiple user-defined regions of interest. Six laser lines (405, 440, 488, 514, 561, & 640nm) and four channel PMT (2x GaAsP, 2x Multi-Alkali) detectors, in addition to a transmitted light channel for laser scanned DIC provide flexible live cell experimental options.

A stage top environmental chamber at 37° C and 5% CO2 required for live cell imaging, coupled with a Perfect Focus system, provides extremely stable long-term imaging without drift. A fast z-piezo and motorized xy stage provides high speed automated multi-location and tiling/stitching acquisitions. Seven laser lines (408, 445, 473, 518, 545, 635, & 750nm), DIC, and phase acquisitions are available. NIS-Elements packaged with analysis options coupled to JOBS enable tailorable data-driven acquisitions.
Nikon N-SIM (Whitehead): The Nikon Structured Illumination Microscope (SIM) doubles the resolution of widefield microscopy in all three dimensions (down to 120 nm x-y and 300 nm z resolution), and can image samples prepared with conventional techniques (same as confocal or widefield). A sensitive iXon EMCCD camera and three laser line system (488, 514, and 561nm) provides high speed multi-color acquisitions. A SIM-TIRF mode is also available. The system also includes a 37°C 5% CO2 and humidity-controlled stage insert, together with heated objectives for the option of live cell super resolution acquisitions.
Deltavision OMX BLAZE (HSRB): The DeltaVision OMX imaging platform is an advanced multi-mode, super-resolution microscope system. DeltaVision OMX provides 4 color super-resolution imaging using 3D structured illumination (3D-SIM) as well as ultra-fast widefield-deconvolution acquisition (3x sCMOS cameras for 300 fps imaging). The OMX Blaze also has Ring-TIRF capabilities to image biological processes at the cell surface-coverslip interface. The laser scanning optics of the TIRF beam path allow for fast switching of photoactivation and photokinetics in combination with live cell widefield-deconvolution, 3D-SIM imaging or TIRF. The system also includes 37°C 5% CO2 and humidity-controlled stage inserts, along with heated objectives for the option of live cell super resolution acquisitions.
3i Lattice Light Sheet (Winship): The Intelligent Imaging Innovations (3i) lattice light sheet microscope (LLSM) is state-of-the-art for rapid high-resolution live cell imaging with low phototoxicity stemming from efficient lightsheet excitation/collection. Compared to a spinning disk confocal, the LLSM features 100x less phototoxicity/photobleaching in dithered mode. The collection objective, a Nikon 25X/1.1NA, is matched with a tube lens for an overall 62.5X magnification with better axial resolution than achievable through confocal microscopes. A one-channel 40x40x40um region can typically be imaged in 1 second. For super-resolution in x and z, a SIM mode is available at the expense of temporal resolution, and super-resolution may also be achieved through Super Resolution Radial Fluctuations (SRRF). The system has four lasers (405, 488, 561, and 642nm) for sequential acquisition with a quad-band bandpass filter. Samples are loaded onto 5mm glass coverslips and immersed in a 3- or 12-mL media bath between the inclined objective lenses.
