IRDye 800CW PEG Contrast Agent is a non-specific imaging agent intended to exploit EPR in tumor biology. In appropriate mouse models, the agent highlights surface vasculature for approximately 0.5 hour post injection. Approximately 4 hours post injection, retention of the labeled macromolecule is visible in the tumor. At 9 hours post intravenous injection the tumor is well defined.
In addition, IRDye 800CW PEG Contrast Agent may also be used effectively as a lymph tracking agent when given intradermally.
