DOTA-LM3
Based on 2 publication(s) in Google Scholar
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. DOTA-LM3 can be used for the synthesis/research of Radionuclide-Drug Conjugates (RDCs).

Solvent & Solubility
H2O : ≥ 100 mg/mL (64.51 mM)
DMSO : 50 mg/mL (32.25 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
