Method and device for isolating a chemically and radiochemically cleaned 68Ga-radionuclide and for marking a marking precursor with the 68Ga-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.
