Leupeptin (hemisulfate)
Product Specifications
UNSPSC Description
Leupeptin hemisulfate is a broad-spectrum, membrane-permeable protease inhibitor. Leupeptin hemisulfate potently inhibits serine, cysteine and threonine proteases. Leupeptin hemisulfate inhibits Mpro (the main protease of SARS-CoV-2) and also has anti-inflammatory activity[1][2][3].
