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 [67]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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
