Leupeptin hemisulfate (Standard)

Leupeptin (hemisulfate) (Standard) is the analytical standard of Leupeptin (hemisulfate). This product is intended for research and analytical applications. 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].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
