  • Publication number: 20110280802
    Abstract: A new and improved method for extending the half life of pharmaceutical compounds for use in diagnostic imaging or therapy uses a novel linker to attach a diagnostic or therapeutic moiety to a targeting peptide or another diagnostic or therapeutic moiety.
