Edotreotide
Based on 2 publication(s) in Google Scholar
Edotreotide is a ligand that selectively targets SSTR2 and can competitively bind to the receptor. Edotreotide mediates the targeted delivery, while modificated with radionuclides (such as 90Y, 177Lu, and 68Ga) to SSTR-positive tumors and induces tumor cell apoptosis by releasing β rays. Edotreotide has strong tumor targeting and precise killing activity. Edotreotide is used in the synthesis of radionuclide-drug conjugates (RDCs) and is widely used in the field of neuroendocrine tumors (such as metastatic carcinoids, lung and thymus NETs).

Solvent & Solubility
DMSO : 100 mg/mL (70.34 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 5 mg/mL (3.52 mM; ultrasonic and warming and heat to 60°C)
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). 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.
