Leupeptin hemisulfate
Trypsin-like cysteine protease inhibitor / A reversible inhibitor of trypsin-like proteases and cysteine proteases. Inhibits trypsin, plasmin, papain and cathepsin B, H and L.1-3 Blocks various apoptotic pathways in T cells.4 Commonly used in cell lysis buffers to protect proteins from degradation. Typical working concentration is 1µM (0.5 µg/ml).
