Radionuclide generator-based production of therapeutic 177Lu from its long-lived isomer 177mLu

Background In this work, a lutetium-177 (177Lu) production method based on the separation of nuclear isomers, 177mLu & 177Lu, is reported. The 177mLu-177Lu separation is performed by combining the use of DOTA & DOTA-labelled peptide (DOTATATE) and liquid-liquid extraction. Methods The 177mLu cations were complexed with DOTA &...
