詳細

General description

A reversible inhibitor of trypsin-like proteases and cysteine proteases. Also known to inhibit activation-induced programmed cell death and to restore defective immune response in HIV⁺ donors. Often used for the inhibition of endoproteinase Lys-C, kallikrein, papain, plasmin, thrombin, cathepsin B, and trypsin. Leupeptin does not inhibit chymotrypsin, elastase, renin, or pepsin. The recommended working range is 10-100 µM for most applications.

Biochem/physiol Actions

Cell permeable: no

Primary Target
trypsin- and cysteine-like proteases

Product does not compete with ATP.

Reversible: yes

Preparation Note

Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short term storage. Aqueous stock solutions are stable for up to 1 week at 4°C or for up to 1 month at -20°C.
