CYN 154806 inhibits SRIF-induced increases in extracellular acidification (EAR) in CHO-K1 cells expressing human sst2 receptors (pKB 7.92). CYN 154806 also blocks SRIF-induced increases [35S]-GTPγS binding in CHO-K1 cell membranes expressing human sst2 receptors as well as rat sst2(a) and rat sst2(b) receptors (pKB 7.81, 7.68 and 7.96, respectively)[2].

Solvent & Solubility
H2O : 12.5 mg/mL (10.44 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 (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.
