Characteristics of SnO2-based 68Ge/68Ga generator and aspects of radiolabelling DOTA-peptides

Eluate of SnO2-based 68Ge/68Ga generator, either by fractionated elution as by ion exchange can be used for labelling DOTA-peptides with 68Ga at a SA of 50 MBq/nmol at >95% incorporation and a RCP of ±90%. SPE columns are very effective to increase RNP.
