Biological Activity: DOTAGA-anhydride is a DOTA-based metal chelator that can bind to radionuclides and is used to prepare radionuclide drug conjugates (RDCs). DOTAGA-anhydride has been successfully used for labeling antibodies (e.g., Trastuzumab (HY-P9907)). DOTAGA-anhydride can be used for the synthesis of a bimodal tag for Single-photon emission computed tomography (SPECT) or PET/optical imaging[1].

DOTA-bis(tert-butyl)ester | 99.25% | DOTA-bis(tert-butyl)ester is a DOTA-based metal chelator that can bind to radionuclides and is used to prepare radionuclide conjugates (RDCs). DOTA-bis(tert-butyl)ester can be conjugated with different salts to form different metal chelators, such as (HY-B1244) hydrochloride to obtain DOTA-MN2. DOTA-MN2 can be reacted with Ga-citrate to obtain radiolabeling. When (67)Ga-DOTA-MN2 is incubated in phosphate buffer solution or mouse plasma for 24 hours, it does not undergo significant decomposition. In the biodistribution experiment of NFSa tumor mice, it has high tumor uptake and rapid plasma clearance, and is a good material for SPECT and PET studies. | ||||||||||||||||||||
