Abstract:Amplification pretargeting has the potential to increase the tracer's accumulation in the tumor. This study aimed to develop a three-step amplification pretargeting strategy in nuclear medicine with a polymer conjugated with multiple copies of peptide nuclear acid (PNA). In this study, the tracer 18 F-labeled complementary PNA ( 18 F-cPNA) was prepared by click-chemistry with high radiochemical purity (>99%) and great stability in vitro. The PAMMA dendrimer generation 4 (G4) was conjugated with multiple copies… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
