PMSF Solution 100mM
Product Description
C7H7FO2S with mol. Wt. 174.2. Powder with purity of >99%. Store powder at 4 degree Celsius, liquid solution at -20 C. A serine protease inhibitor with multiple biological applications.
PMSF in 10 ml of 100% ethanol. Store in aliquots up to 2 ears at -20oC.
Make fresh dilutions from the alcohol stock for each use because the half-life of PMSF in aqueous solution is <30 min at room temperature and a few hours on ice.
If PMSF is being added to a solution without detergent, the solution should be stirred vigorously during PMSF addition because PMSF has a tendency to form an insoluble precipitate in aqueous solution.
