Method and Device For Isolating a Chemically and Radiochemically Cleaned 68 Ga-Radionuclide and For Marking a Marking Precursor With the 68 Ga-Radionuclide

摘要

The invention relates to initial ⁶⁸Ge/Ga-generator elute which is guided directly to a cation exchanger, whereon ⁶⁸Ga is quantitatively absorbed and is cleaned simultaneously in a chemical and radio chemical manner. Subsequently, the ⁶⁸Ga-radio nuclide is combined with a radio pharmaceutical substance by a marking precursor made of a ligand or a peptide or a protein which is cross-linked in a covalent manner to a ligand.
