Description

Application

Recommended concentrations for use are 0.1-1 mM.

Biochem/physiol Actions

Irreversible serine protease inhibitor. Inhibition constants are similar to those of PMSF and DFP. AEBSF has been shown to inhibit trypsin, chymotrypsin, plasmin kallikrein and thrombin. As an alternative to PMSF and DFP, AEBSF offers lower toxicity, improved solubility in water and improved stability in aqueous solutions. AEBSF has been used in cell culture in concentrations of up to 0.25 mM.

Packaging
