My lab recently purchased 100mg (as a powder) of the MAPK/MEK inhibitor PD0325901. It is recommended to store at -20 for up to 3 months.
The problem is I only just realised for the last 4 weeks it has been incorrectly stored at 4*C in our normal lab fridge.
Does anybody have an idea how stable this inhibitor is, and if this period at 4*C would have reduced its function?
Thanks for any tips!
