INTRODUCTION: Our objective was to evaluate the tumor and normal tissue distribution and nuclear importation properties of [(111)In]-mouse IgG (mIgG) conjugated to tat peptides (GRKKRRQRRRPPQGYG) in athymic mice with subcutaneous BT-474 human breast cancer xenografts. METHODS: Tumor and normal tissue uptake was compared after intravenous (iv) or intratumoral injection of [(111)In]-mIgG-tat and [(111)In]-mIgG. Area under the curve (AUC) was estimated for blood, liver, spleen, kidneys and tumo...Expand abstract
