In Vitro: H2O : 25 mg/mL (41.36 mM; Need ultrasonic) DMSO : 10 mg/mL (16.54 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO) Preparing Stock Solutions
View the Complete Stock Solution Preparation Table * 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. * 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.
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol) Concentration (start) × Volume (start) = Concentration (final) × Volume (final) This equation is commonly abbreviated as: C1V1 = C2V2 In Vivo: Select the appropriate dissolution method based on your experimental animal and administration route. For the following dissolution methods, please ensure to first prepare a clear stock solution using an and then sequentially add co-solvents:
For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
In Vivo Dissolution Calculator Please enter the basic information of animal experiments: Dosage mg/kgAnimal weight Dosing volume Number of animals Recommended: Prepare an additional quantity of animals to account for potential losses during experiments.
