Maleimide-DTPA

Bifunctional Chelator

Maleimide-DTPA is a bifunctional chelator that enables the conjugation of peptides with radionuclides for targeted imaging and therapeutic applications. The maleimide group allows for selective attachment to thiol-containing biomolecules, facilitating the stable chelation of indium-111 (111In). This compound demonstrates high stability when complexed with peptides in biological environments, making it a valuable tool for medical imaging and development of radionuclide conjugates. Its utility in peptide labeling enhances research in nuclear medicine and targeted radiotherapy.
