Uses
DOTATATE acetate is a DOTA-conjugated peptide. DOTATATE acetate can be labelled with radionuclides for positron emission tomography (PET) imaging and peptide receptor radionuclide research (PRRT)[1][2][3][4]. DOTATATE (acetate) can be used for the synthesis/research of Radionuclide-Drug Conjugates (RDCs).
in vivo
177Lu-DOTATATE shows excellent antitumor effects in rats[1].
