Preparation, In Vitro Affinity, and In Vivo Biodistribution of Receptor-Specific 68 Ga-Labeled Peptides Targeting Vascular Endothelial Growth Factor Receptors.

. We found both radiolabeled peptides very potent in their receptor binding, which makes them suitable imaging agents. The rapid transition of the radiopeptides into the urinary tract indicates suitable pharmacokinetic characteristics.
