Pre-clinical evaluation of immunoPET imaging using agonist CD40 monoclonal antibody in pancreatic tumor-bearing mice

A novel [64Cu]Cu-NOTA-aCD40 immunoPET tracer was developed to image a CD40+ pancreatic tumor model in C57BL/6 mice and to study the biodistribution profile of the agonist CD40 (aCD40) monoclonal antibody (mAb) alone or combined with other mAbs.Copper-64 ([64Cu]Cu) labeled NOTA-aCD40 and NOTA-IgG (10 μg; 7 MBq) were injected intravenously into C57BL/6 mice with subcutaneous mT4 tumors to assess specificity 48 h post injection (p.i.) through...
