LI-COR Biosciences has introduced a new accessory and IRDye reagents for in vivo molecular imaging on its Odyssey Infrared Imaging System. The Odyssey MousePOD Imaging Accessory fits over the standard Odyssey scanning surface for in vivo imaging of up to three mice. Longitudinal studies are facilitated by MousePOD temperature regulation and easy connection to a gas anesthesia system. New software includes tools to quickly mark and quantify regions of interest such as tumors. IRDye reagents for in vivo imaging include infrared dyes for labeling probes, an IRDye 800 CW labeling kit, and the new IRDye 800CW EGF Optical Probe. Together with the Odyssey System and MousePOD, these reagents provide a solution for cellular analysis that includes optical tracer characterization using the In-cell Western assay, in vivo imaging, imaging whole tumors, and in situ analysis and characterization of tumor sections. The Odyssey system itself is equipped with two infrared channels for direct fluorescence detection with high sensitivity and low biological background fluorescence.
