DOTA-LM3 is a somatostatin receptor (SSTR) antagonist. LM3 refers to p-Cl-Phe- cyclo(D-Cys-Tyr-D-4-amino-Phe(carbamoyl)-Lys-Thr-Cys)D-Tyr- NH2, as well as a somatostatin antagonist. DOTA-LM3 is often isotopically labeled for tracing tumors in vivo, such as 177Lu-DOTA-LM3 and 68 Ga-DOTA-LM3. 68 Ga-DOTA-LM3 shows favorable biodistribution, high tumor uptake, good tumor retention, and few safety concerns. 177Lu-DOTA-LM3 can be used for research in DOTATOC-negative liver metastases, such as pancreatic NET and extensive tumor thrombosis.

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.
