[Leu15]-Gastrin I (human)
Based on 1 publication(s) in Google Scholar
[Leu15]-Gastrin I (human) is a Gastrin I, human (HY-P1097) peptide hormone derivative, which is trophic for normal gastrointestinal epithelium. Gastrin stimulates growth of gastric adenocarcinoma (gastric cancer) through G-protein-coupled receptor called the cholecystokinin (CCK) or cholecystokinin-B receptors (CCK-BR) that are overexpressed in this malignancy. [Leu15]-Gastrin I (human) is promising for research of gastric cancer.

Solvent & Solubility
DMSO : 100 mg/mL (48.07 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 10.53 mg/mL (5.06 mM; ultrasonic and adjust pH to 11 with NaOH)
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.
