For example, if the dosage of your experiment is 10mg/kg, the weight of each animal is 50g, and the volume of the dosing is 100μL, then the working solution concentration of your experiment is 5mg/mL. If the formula you used is 5% DMSO+ 30% PEG300+ 5% Tween 80 + 60% Saline/PBS/ddH2O, the preparation method is as follows:
Mother liquor preparation method: 5mg of drug dissolved in 100μL DMSO (mother liquor concentration is 50mg/mL). Preparation method of in vivo formulation: For 1mL of working solution preparation, take 50μL of DMSO mother liquor, add 300 μL of PEG300 to mix well and clarify, then add 50μL of Tween-80 to mix well and clarify, and finally add 600μL of Saline/PBS/ddH2O to mix well and clarify.Note:
- For Reference Only. Please choose the appropriate dissolution protocol according to your experimental animal and administration method.
- We suggest that in cell experiments, the final concentration of DMSO is not more than 0.1%, in animal experiments, for healthy mice, the final concentration of DMSO is not more than 10%; For nude or frail mice, the final concentration of DMSO is not more than 2%.
