商品描述
Protease inhibitor of serine and cysteine proteases.
Leupeptin inhibits serine and thiol proteases such as trypsin, plasmin, proteinase K, kallikrein, papain, thrombin, and cathepsin A and B.
Not affected are α-, β-, γ- and δ- chymotrypsin, pepsin, cathepsin D, elastase, renin, and thermolysin.
Effective concentration 10-100 μM.
Application
Leupeptin as well as other protease inhibitors like pepstatin are useful for the protection of proteins during their isolation from tissues or membranes. Leupeptin can be removed from the reaction by dialysis.
