AEBSF (Aminoethyl-Benzenesulfonyl Fluoride Hydrochloride)
AEBSF or 4-(2-aminoethyl) benzenesulfonyl fluoride hydrochloride is a water-soluble, irreversible serine protease inhibitor with a molecular weight of 239.7 Da. It inhibits proteases like chymotrypsin, kallikrein, plasmin, thrombin, and trypsin. The specificity is similar to the inhibitor PMSF, nevertheless AEBSF is more stable at low pH values. Typical usage is 0.1 – 1.0 mM.
