Basic Info

What is Phenylmethylsulfonyl Fluoride?

Phenylmethylsulfonyl fluoride (PMSF) is an irreversible serine protease inhibitor, such as chymotrypsin, trypsin, thrombin, etc., the principle of action is to specifically recognize and sulfonate the active site of serine residues that determine enzyme activity. In addition, it has inhibitory effects on cysteine proteases (such as papain, whose inhibitory activity is reversed by DTT) and acetylcholinesterase of mammalian origin. PMSF is often added to the lysate before cell or tissue lysis to prevent protein degradation. PMSF can be used alone or in combination with other protease inhibitors such as aprotinin A or phosphatase inhibitors such as sodium orthovanadate.

This product is provided in powder form, it is insoluble in water, and its stability in aqueous solution is very poor, so it must be added to lysate or other aqueous solutions before use. PMSF powder can be dissolved in methanol, ethanol or isopropanol to prepare stock solution (such as 200 mM), and the effective working concentration is 0.1-1 mM.

Another non-toxic substitute for PMSF, AEBSF, is an irreversible serine protease inhibitor with the same activity and function as PMSF, and is easily soluble in water.

Phenylmethylsulfonyl Fluoride Uses

  1. Phenylmethylsulfonyl fluoride can inhibit serine proteases such as trypsin and chymotrypsin, as well as cysteine proteases and acetylcholinesterase. The effective concentration is 0.1-1mM.
  2. Specifically recognizes and sulfonates the active site of serine residues that determine enzyme activity. In addition, it has inhibitory effects on cysteine proteases (such as papain, whose inhibitory activity is reversed by DTT) and acetylcholinesterase of mammalian origin. PMSF is often added to the lysate before cell or tissue lysis to prevent protein degradation. Phenylmethylsulfonyl fluoride can be used alone or in combination with other protease inhibitors such as aprotinin A or phosphatase inhibitors such as sodium orthovanadate.
