Receptor-targeted optical imaging of tumors with near-infrared fluorescent ligands


We report here the in vivo diagnostic use of a peptide–dye conjugate consisting of a cyanine dye and the somatostatin analog octreotate as a contrast agent for optical tumor imaging. When used in whole-body in vivo imaging of mouse xenografts, indotricarbocyanine-octreotate accumulated in tumor tissue. Tumor fluorescence rapidly increased and was more than… (More)
