Frequently Asked Questions

Question 1:
Can you let me know what solvent I can use for it, cat # S1147, for in vivo use? (IP injection in mice)

Answer:
S1147 can be dissolved in 30% PEG400/0.5% Tween80/5% Propylene glycol at 30mg/ml as a clear solution. Usually, when prepare the solution, we will add organic solvents first, then add Tween 80, then water. But this compound can not dissolve in 30% PEG400/0.5% Tween80/5% Propylene glycol clearly. After water was added, it became a clear solution.
