Background

Cellular crude extracts contain numerous endogenous enzymes, such as phosphatases and proteases, capable of degrading proteins in the extracts. The most effective strategy to enhance the yield of intact proteins is through the addition of inhibitors targeting these known endogenous enzymes.The Protease Inhibitor Cocktail is intended for the purification of His-tagged proteins to improve protein stability. This cocktail functions by inhibiting proteases that degrade either phosphorylated or non-phosphorylated protein substrates.

This Protease Inhibitor Cocktail contains individual components including AEBSF, Bestatin, E-64, Phosphoramidon, and Pepstatin A, offering broad-spectrum specific inhibition against cysteine, serine, aspartic, thermolysin-like proteases, and aminopeptidases. It has been optimized and validated specifically for use with His-tagged proteins. The cocktail is dissolved in DMSO and supplied as a ready-to-use solution.
