UsesDOTATATE is a DOTA-conjugated peptide. DOTATATE can be labelled with radionuclides for positron emission tomography (PET) imaging and peptide receptor radionuclide research (PRRT)[1][2][3][4]. DOTATATE can be used for the synthesis/research of Radionuclide-Drug Conjugates (RDCs).
in vivo

177Lu-DOTATATE shows excellent antitumor effects in rats[1].
