Leupeptin Hemisulfate CAS 103476-89-7

Product Overview

• Leupeptin Hemisulfate (CAS 103476-89-7) is a reversible and competitive protease inhibitor capable of inhibiting serine and cysteine proteases, including plasmin, trypsin, papain, and calpain. It features a peptide-like sequence terminating in a reactive C-terminal aldehyde group, which forms a reversible covalent bond with the active site residues of target enzymes. And it is utilized in cell lysis buffers and enzyme assays to prevent non-specific proteolytic degradation of target proteins during extraction and purification procedures.
• As a professitional manufacturer of Leupeptin Hemisulfate in China, Conscientia Industrial utilizes solid-phase peptide synthesis (SPPS) and advanced liquid chromatography isolation technology to ensure superior quality and batch-to-batch consistency.
