Calculation results:

• Working concentration: mg/ml;
• Method for preparing DMSO master liquid: mg drug pre-dissolved in µL DMSO (Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.)
• Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL PEG300, mix and clarify, next add µL Tween 80, mix and clarify, next add µL ddH2O, mix and clarify.
• Method for preparing in vivo formulation: Take µL DMSO master liquid, next add µL Corn oil, mix and clarify.

Note:

• Please make sure the liquid is clear before adding the next solvent.
• Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
