* In solvent : -80°C, 6 months; -20°C, 1 month (protect from light, stored under nitrogen)
Solvent & Solubility
H2O : 100 mg/mL (839.49 mM; Need ultrasonic)
DMSO : < 1 mg/mL (insoluble or slightly soluble)
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, stored under nitrogen). 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.
