If I were to dissolve 20mg of non-water soluble extract in DMSO to test on fungus, what percentage of DMSO should i used?
Hi,
1% is a maximum concentration and 0.1% is safe. What volume do you want to dissolve 20mg? Maybe you should dilute your DMSO stock solution in 1% polysorbate 20 or 80 to avoid extract precipitation.
Good luck!
