Descripción general

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.

Aplicación

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.

Acciones bioquímicas o fisiológicas

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).

Questions

1–6 of 6 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

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

    1 answer

    1. 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.
