Figure 5. Targeting of fluorescently labeled trimerbodies to CEA negative human tumor xenografts in nude mice.

Near-infrared fluorescence imaging of nude mice bearing s.c. HT1080 human fibrosarcoma tumors (A) or HeLa human cervical adenocarcinoma tumors (B). Imaging was performed at 3, 24, and 48 hours after i.v. injection with Cy5-labeled trimerbodies.
