Application

1,4,7,10-Tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) is a macrocyclic complexing agent.
  • It has been used for radiolabeling of carbon nanotube bioconjugates by chelating 64Cu radioisotope.
  • DOTA can be activated with N-hydroxysulfosuccinimidyl for conjugation with monoclonal antibodies in clinical radioimmunotherapy.
  • It can form complexes with gadolinium for application as MRI contrast agents.
  • Metal complexes of DOTA-peptide conjugates can be used as therapeutic radiopharmaceuticals.
