Inhibitor for Trypsin, Plasmin, Papain, and Cathepsin B

Leupeptin, is a microbial product isolated and purified usually as hemisulfate. The tripeptide aldehyde is highly soluble in commonly used buffers containing Water, Ethanol, or DMF. Leupeptin will be used in combination with Pepstatin A in protease inhibitor cocktails like "Mito Buffer" or "TNC Buffer".
The purity of Leupeptin cannot be determined by HPLC or TLC due to three tautomeric isomers which will be separately detected.
