PMSF dire straits

Dear Protein experts,

I am currently running experiments requiring the use of PMSF. I have to
prepare fresh
solutions each time which as you may know takes up time and wastes a lot of
the
reagent. Is there a way to prepare a solution which is stable in storage?
are there other similar protease inhibitors? I am specifically interested in
stability of PMSF in methanol,  acetone and isopropanol over time. I have
heard some colleagues store such solutions for up to a month, but I need
confirmation from the scientific body.

Kindly, please respond to my email address:

Best regards,

Dr. Margaret Simm, PhD
