General description

Leupeptin is a water-soluble and cell-permeable organic compound.[1] It is produced by various species of actinomycetes and several other fungal families.[2]

Application

Leupeptin has been used as a protease inhibitor supplement in cell lysis buffer for sample preparation.[3][4][5]

Biochem/physiol Actions

Leupeptin serves as a lysosomal protease and calpain (serine- and cysteine-like protease) inhibitor.[6][1] It may be used to reduce the cell death induced by excess calpain activation. Leupeptin confers significant protection against hair cell damage caused by gentamicin ototoxicity.[1] In addition, it also impedes protein degradation in denervated rat muscles and muscles of mice with hereditary muscular dystrophy. Thus, leupeptin may be beneficial in hindering tissue atrophy.[7]

Physical form

Lyophilized.

Preparation Note

Maintain dry at -20ºC for up to 18 months after date of receipt. Store reconstituted product in aliquots at -20ºC for up to 6 months. Avoid repeated thaw freeze cycles.

Western Blotting Tools

Western blotting is one of the most commonly used techniques in the lab, yet difficulties persist in obtaining consistent, quality results. We’ve been helping scientists publish their Western blots for decades, with continued innovation and steadfast technical support. Explore our expanded portfolio of products, including optimized reagents for chemiluminescent and Ḁuorescent Westerns, as well as the SNAP i.d.® system, which reduces blocking, washing and antibody incubation time from hours to minutes.

The protease inhibitor leupeptin decreases protein degradation in rat skeletal and cardiac muscle incubated in vitro, while protein synthesis remains unaltered. Leupeptin also lowers protein breakdown in denervated rat muscles and affected muscles from mice with hereditary muscular dystrophy. Leupeptin

Leupeptin is a naturally occurring inhibitor of various proteases, in particular serine proteases. Following its discovery, the inhibitory properties of several other peptidyl argininals have been studied. The specificity of leupeptin is most likely due to the Leu-Leu-Argininal sequence, and
