Solvent & Solubility
1M HCl : 50 mg/mL (381.18 mM; ultrasonic and adjust pH to 1 with HCl)
H2O : 10 mg/mL (76.24 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, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.
* 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.
