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.

Note:

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
