Description and Uses

Leupeptin hemisulfate (103476-89-7) is 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).

Leupeptin has been used as a protease inhibitor: in ice-cold lysis buffer to harvest cells for western immunoblotting and immunoprecipitation,in chromatin immunoprecipitation (ChIP) lysis buffer for the isolation of fragmented chromatin samples in lysis buffer I to lyse the cells for tandem affinity purification (TAP)
