MediLumine’s EMCCD based PRISM™ uses photon counting for highly sensitive in vivo optical imaging of up to five mice. The imager is able to detect a single photon in a pixel opening a new biological window for bioluminescence and fluorescence imaging.

In addition, the imaging system is sensitive at high acquisition speeds allowing for real-time imaging in bioluminescent and fluorescence modes.

User’s of PRISM are finding that the system has an unparalleled combination of real-time imaging and detection of ultra-weak photonic emissions for deeper and earlier in vivo imaging. The design of PRISM is completely modular allowing scientists to purchase either base Bioluminescent imager or Bioluminescent and Epi-Fluorescent System or Bioluminescent with Epi- and Trans-Fluorescent modules for NIR fluorescent 3D imaging.

Tumor cells were injected i.v. and time-lapse in vivo images of lung and liver tumor growth were detected by luminescence (luciferase) in mice without immune reconstitution (no-AT), injected i.v. with 1 × 106 MSCs following Auto-AT of 1 × 107 WBC (Auto-AT) or with AT of WBC and the injection of MSCs (Auto-AT plus MSC). Also shown are images of tumors by fluorescence (mPlum) at sacrifice. ref.
