DOTA-NHS ester is a powerful chelating agent used in radiolabeling and bioconjugation . It combines a DOTA group that binds radiometals like Gallium-68 and Lutetium-177 with an NHS ester that reacts with primary amines on proteins and peptides. This setup enhances targeted delivery in imaging and therapeutic applications, making it ideal for PET, SPECT , and radiotherapy .
