ABSTRACT Scientific innovations in diagnostic methods are important drivers of cancer control and prevention. Noninvasive imaging of the epidermal growth factor receptor (EGFR) in head-and-neck squamous, cell carcinoma and colorectal cancer could be valuable to select patients for EGFR-targeted therapy, as well as to monitor the efficacy and occurrence of resistance to immunotherapy. In order to develop the first Brazilian radioimmunoconjugate for diagnosis, Cetuximab has been conjugated to p-SCN-Bn-DTPA chelator and radiolabeled with Indium-111. The conjugation methodology was optimized using different mAb:DTPA molar ratios, time was then reduced for immunoconjugate preparation, besides the protein recovery’ percentage increased after purification (m =... |
