Tetraxetan
Based on 1 publication(s) in Google Scholar
Tetraxetan (DOTA) is a macrocyclic chelating agent. Tetraxetan can form stable coordination complexes with a variety of metal ions (e.g., 68Ga, 111In, 177Lu). Tetraxetan can be conjugated with targeting molecules (e.g., RGD peptide, folic acid) to enable the complex to target specific biomolecules or cells. Tetraxetan can be used for imaging studies of tumors, including melanoma and folate receptor-positive tumors (e.g., cervical cancer) .

Solvent & Solubility
H2O : 100 mg/mL (247.27 mM; Need ultrasonic)
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 (protect from 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.
