설명

일반 설명

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.

A reversible inhibitor of trypsin-like proteases and cysteine proteases. Also known to inhibit activation-induced programmed cell death and to restore defective immune responses of HIV⁺ donors. Also available as a 50 mM solution in H₂O (Cat. No. 509281).
