General description

Protease Inhibitor Cocktail for mammalian cell and tissue extracts, in DMSO solution. It contains six individual components for inhibiting serine, cysteine, and acid proteases, and aminopeptidases.

Specificity

Inhibits serine, cysteine, and acid proteases, and aminopeptidases.

Application

Ideal for use as a buffer component during sonication, lysis buffer, and RIPA buffer

Provides protection against endogenous enzyme activity in cell and tissue extracts

Biochem/physiol Actions

This mixture contains individual components, including AEBSF at 104 mM, Aprotinin at 80 μM, Bestatin at 4 mM, E-64 at 1.4 mM, Leupeptin at 2 mM and Pepstatin A at 1.5 mM. Each component has specific inhibitory properties. AEBSF and Aprotinin act to inhibit serine proteases, including trypsin, chymotrypsin, and plasmin amongst others. Bestatin inhibits aminpeptidases. E-64 acts against cystein proteases. Leupeptin acts against both serine and cystein proteases. Pepstatin A inhibits acid proteases.

Features and Benefits

Broad-spectrum inhibition: inhibits multiple classes of proteases and aminopeptidases

Stable storage: supplied as a solution in DMSO, allowing for long-term storage at -20°C

Consistent performance: ready-to-use solution
