DOTA-​NHS-ester TFA

DOTA-NHS-ester (TFA) is a bifunctional chelator linker used to conjugate affibody molecules with radionuclides like Gallium-68 or Indium-111 for creating targeted imaging probes. Its primary research application is in the development of radiopharmaceuticals for in vivo tumor detection via PET and SPECT in preclinical models.
