DOTA Bifunctional Chelators
Our DOTA-dPEG® products combine the functionality of the DOTA, an effective metal-chelating macrocyclic compound, with our single molecular weight discrete PEG (dPEG®) products containing a useful reactive group for conjugation to biomolecules. These products enable many different diagnostic and therapeutic applications, including the following:
- MRI contrast agent when complexed with Gadolinium;
- radioimmunotherapy agents when conjugated to antibodies and complexed with suitable metals;
- PET and SPECT imaging agents; and,
- radiotherapeutic agents when conjugated to peptides and complexed with appropriate metals.
Our high-purity dPEG® products increase water solubility and reduce or eliminate the immunogenicity of conjugate molecules. To learn more about these products, please read our page titled, “DOTA-tris(TBE) or DOTA-tris(acid)? Choose wisely.” Try our DOTA-dPEG® line of products today and discover the dPEG® difference.
