MET and cancer: Jagoda et al.36used 76Br and 89Zr for the radiolabeling of onartuzumab in 2012 and tested the labeled monoclonal antibody against c‐Met overexpressing human cancer cell lines and xenografted mouse models. Onartuzumab was labeled with 89Zr using desferrioxamine as chelating moiety while 76Br was directly covalently bonded.
