The Zeiss Axiovert 200 is an inverted epi-fluorescence microscope. Images can be aquired with the AmScope MU-1000 USB 3.0 and AmScope Software or Hamamatsu ORCA-ER digital camera and AxioVision software. The ORCA-ER digital camera is a high resolution gray scale camera.

Standard objectives on this system include:

10x Plan Apochromat, 0.45, Ph1
20x Plan Apochromat, 0.8, Ph2
40x C-Apochromat, 1.2W, oil, DIC
63x Plan-Apochromat, 1.4, oil, DIC

Also located in the Multimodal Imaging Suite at CBBI:

The Zeiss LSM 780 is an upright confocal with 32 channel ultra sensitive GaAsP detectors that allow visualization of weak fluorescent signals with lower photobleaching and phototoxicity. In addition, the system can be used for spectral imaging, photon counting and fluorescence correlation spectroscopy (FCS). The added Multiphoton laser is a 3 Watt Chameleon Vision II with a range of 680 - 1080 nm. The NDD detection system can be used for imaging multiphoton florescence or detection of second harmonic generation (SHG) in the forward and reverse directions. Furthermore, the new OSCiscan function allows faster acquisition of high quality data and better time resolution.

Laser Lines: 405 nm, 458 nm, 488 nm, 514 nm, 561 nm, 633 nm

The SkyScan 1276 is a high performance, stand-alone, fast, desk-top in vivo micro-CT with continuously variable magnification for scanning small laboratory animals (mice, rats, hamster, etc.) and biological samples.

It features a combination of high resolution, big image size, round/spiral scanning, reconstruction, and low dose imaging.

The image field of view (up to 80 mm wide and more than 300 mm long) allows full body mouse and rat scanning.

The variable magnification allows scanning bone and tissue samples with high spatial resolution down to a 2.8 µm pixel size.

Variable X-Ray energy combined with a range of filters ensures optimal image quality for diverse research applications from lung tissue to bone with metal implants.

The SkyScan 1276 in vivo micro-CT administers low radiation dose to the animals allowing multiple scans in longitudinal preclinical studies without the risk of unwanted radiation-induced side effects.

The system can perform scanning with continuous gantry rotation and in step-and-shoot mode with the fastest scanning cycle 3.9 sec.

Attached, dedicated gas anesthesia unit for intravital imaging.

The IVIS ® Lumina Series III brings together years of leading optical imaging technologies into one easy to use and exquisitely sensitive bench-top system. The IVIS Lumina III is capable of imaging both fluorescent and bioluminescent reporters. The system is equipped with up to 26 filter sets that can be used to image reporters that emit from green to near-infrared. Superior spectral unmixing can be achieved by Lumina III’s optional high resolution short cut off filters.

Features:

Exquisite sensitivity in bioluminescence
Full fluorescence tunability through the NIR spectrum
Compute Pure Spectrum spectral unmixing for ultimate fluorescence sensitivity
Dedicated XGI-8 Gas Anesthesia System
