How do I prepare and store dexamethasone used in the hepatocyte media?

For use with iCell® Hepatocytes 2.0, you can prepare a 5 mM stock solution of dexamethasone in DMSO, vortex to mix, and then dispense and store aliquots at -20°C for up to 1 year. Thawed aliquots are stable at 4°C for 1 month. Do not subject aliquots to more than a single refreeze and thaw cycle.
