  Our previous study demonstrated the therapeutic efficacy of 177Lu-DOTA-gluBBN for the treatment of GRPRexpressing prostate tumors. As a matched pair for 177Lu, the development of labeling and molecular imaging technology using 68Ga is needed to introduce the “theranostic” approach. Therefore, the present study described the 68Ga-labeled bombesin analog, 68Ga-DOTA-gluBBN for the imaging of GRPR-expressing prostate tumors. Methods: 68Ga was concentrated and labeled with DOTA-gluBBN using the NaCl method, and the labeling yield was evaluated by iTLC-SG. Human prostate PC-3 tumor cells were used to induce a subcutaneously xenografted-tumor model and a peritoneal metastasized tumor model. PET-CT imaging studies were performed in both animal models. Results: Eluted 68Ga solution containing 5~10% of impurities.. View More»
