LexinPharma can manufacture chelator-modified peptides as a starting material for radiolabeled peptides or peptide
radiotracers. Some examples include synthesis of DOTA/NODAGA-functionalized peptides. These peptides are
then often later radiolabeled with 68Ga or 177Lu and used for tumor imaging for diagnosis and therapy or
theranostics such as peptide receptor radionuclide therapy (PRRT). Other modifications include peptides modified with di-iodo-Tyr, dehydro-Leu, or dehydro-Pro for reductive tritiation, peptide resin for N-terminal capping with C14-acetic anhydride, and peptides modified for click chemistry
introduction of radioactive fluorine isotopes. Contact us to learn more about our capabilities in peptide synthesis.
