Tumor imaging using a standardized radiolabeled adapter protein docked to vascular endothelial growth factor.
J Nucl Med. 2004; (8): 1373-80
Direct radiolabeling of proteins can result in the loss of targeting activity, requires highly customized procedures, and yields heterogeneous products. Here we describe a novel imaging complex comprised of a standardized (99m)Tc-radiolabeled adapter protein noncovalently bound to a "Docking tag" fused to a "Targeting protein". The assembly of this complex is based on interactions between human 109-amino acid (HuS) and 15-amino acid (Hu-tag) fragments of ribonuclease I, which serve as an "Adapter protein" and a Docking tag, respectively.
