MET and non-small cell lung carcinoma: scFv‐cysdimers H2, a human single‐chain variable fragments‐cys‐diabody was radiolabeled with 89Zr and studied in xenografts mouse models by Li et al.38The cys‐diabody was labeled with the radiometal using a deferoxamine‐maleimide covalently bonded to the antibody.89Zr‐DFO‐H2 cys‐diabody uptake was studied in Hcc827‐GR6 (human NSCLC with high c‐Met expression resistant to gefitinib) and Hcc827 tumors (human NSCLC with low c‐Met expression).
