For a 200 mM (200X) stock solution, reconstitute the 34.84 mg of lyophilized PMSF supplied in the product tube in 1 mL isopropyl alcohol. PMSF is unstable in water and should be added to lysis buffers or other aqueous solutions just prior to use. Typically, a final concentration of 1 mM provides sufficient protease protection. Store lyophilized at RT for 24 months protected from direct light. Once in solution, PMSF can be stored at -20ºC for up to 3 months, protected from light.
