WGK 1
CAS No. [103476-89-7]


Reversible inhibitor of serine- and cysteine proteases.
Application: Stock solution: 5 mg/ml (10 mM) in H2O, ethanol, acetic acid and DMF. Stock solution is stabile at +4 °C for approx. 7 days. Recommended storage of stock solution at -20 °C (6 months). Working concentration: 0.5-50 µg/ml (1-100 µM). Working solutions are stabile only for few hours. Due to its aldehyde groups, leupeptin may interfere with protein detection assays (e.g. Bradford).
Leupeptin hemisulphate ≥96,5 %, for biochemistry

Leupeptin competitively inhibits calpain, cathepsin B, kallikrein, papain, plasmin and trypsin. Inhibition of thrombin is controversely discussed. Little or non-inhibiting for pepsin, cathepsin A and D and chymotrypsin.
