Application

4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF) has been used:
  • as a protease inhibitor in plasma samples to prevent acylated ghrelin (AG) degradation
  • as a snake venom serine proteinase (SVSP) inhibitor in SVSP inhibition or AEBSF assay to test the involvement of SVSPs on the fibrinogen-clotting activity
  • as a component in NP-40 lysis buffer to resuspend cell pellets for preparing cell lysates

Recommended concentrations for use are 0.1-1 mM.

Biochem/physiol Actions

4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride (AEBSF) is an irreversible serine protease inhibitor. Inhibition constants are similar to those of phenylmethanesulfonyl fluoride (PMSF) and diisopropylfluorophosphate (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 can be used in cell culture in concentrations of up to 0.25 mM.
AEBSF can inhibit acetylcholinesterase (AChE).

General description

stable for up to six months if stored refrigerated at a pH of less than 7. If a pH of greater than 7 is required, pH adjustment should be made just prior to use.

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. In what solvents is Product A8456, 4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride, soluble?

    It is highly soluble in water and in DMSO, at 50 mg/mL (approximately 200 mM), yielding a clear colorless solution. AEBSF may be used in cell culture medium at concentrations up to 0.25 mM.  

  4. How stable is Product A8456, 4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride, in solution?

    Solutions in water are slightly acidic and retain inhibitory activity for up to six months when stored refrigerated. Solutions at pHs above 7 are less stable.  Stock solutions should be stored at a pH less than 7. If a final pH of greater than 7 is required, the pH adjustment should be done shortly before use.

  5. What is the recommended working concentration for Product A8456, 4-(2-Aminoethyl)benzenesulfonyl fluoride hydrochloride?
