The Xenogen IVIS® Spectrum in vivo imaging system from Caliper Life Sciences uses Xenogen’s novel patented optical imaging technology to facilitate non-invasive longitudinal monitoring of disease progression, cell trafficking and gene expression patterns in living animals. Quantitative monitoring of both bioluminescent and fluorescent probes and reporters across the blue to almost infrared wavelength spectrum is possible. NOTE: GFP is not recommended for most fluorescent imaging applications; alternatively, plan to use a red shifted fluorescent protein such as cherry, tomato, or katushka. The Spectrum is equipped with a gas anesthesia unit that allows continuous administration of isoflurane gas for anesthetizing animals during imaging. The system’s Living Image 4.0 image acquisition and analysis software includes features for spectral unmixing to remove unwanted autofluorescence and to observe and separate several fluorescent and bioluminescent reporters within the same animal. It can also create 3D tomography images that permit source localization and concentration, as well as anatomical analysis using a 3D mouse atlas.


  • High-sensitivity in vivo imaging of fluorescence and bioluminescence
  • High throughput (5 mice) with 23 cm field of view
  • High resolution (to 20 microns) with 3.9 cm field of view
  • Twenty eight high efficiency filters spanning 430 – 850 nm - Supports spectral unmixing applications - Ideal for distinguishing multiple bioluminescent and fluorescent reporters
  • Optical switch in the fluorescence illumination path allows reflection-mode or transmission-mode illumination
  • 3D diffuse tomographic reconstruction for both fluorescence and bioluminescence that can be analyzed in an anatomical context using The Digital Mouse Atlas.
  • Ability to import and automatically co-register CT or MRI images yielding a functional and anatomical context for your scientific data.
  • NIST traceable absolute calibrations
  • Gas anesthesia inlet and outlet ports

The instrument is equipped with the XGI-8 Gas Anesthesia Module, which integrates efficient gas delivery while minimizing excess gas exposure to lab personnel into a single system. The Gas Anesthesia System delivers isoflurane gas to a 5-port anesthesia manifold (for work with mice) housed in the IVIS System imaging chamber.
