General description

AEBSF >99%; 30827-99-7
Specific irreversible inhibitor of serine proteases. Reacts covalently with a serine at the active site. Inhibits chymotrypsin, kallikrein, plasmin, thrombin, trypsin, and related thrombolytic enzymes. Stable, nontoxic alternative to PMSF (Cat. No. 52332) and DFP (Cat. No. 30967). Used at the same molar concentration (0.1-1.0 mM) as PMSF for most applications. Exhibits low inhibitory activity towards proteinase K. A material with ≥97% purity by HPLC (Cat. No. 101500) & its InSolution is also available (Cat. No. 508436).
