DOTATATE (acetate)

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) .
