General description

Our Protease Inhibitor Cocktail is a mixture of individual components optimized and tested for use with plant tissue and cell extracts. The cocktail contains a broad specificity of inhibitory properties including serine, cysteine, aspartic and metalloproteases, and aminopeptidases. The individual components include AEBSF, 1,10-Phenanthroline, Pepstatin A, Leupeptin, Bestatin, and E-64.

Specificity

Inhibits serine, cysteine, and aspartic proteases, metalloproteases, and aminopeptidases

Application

This product has been specifically tested on plant seedling extracts from pea, bean, wheat, tobacco, and Arabidopsis, as well as leaf and root extracts from pea, wheat, and tobacco. The recommended quantity is one mL of solution for the inhibition of protease activity in 100 mL of cell lysate from 30 g of various plant tissues or 10 g of baculovirus-infected cells.

Biochem/physiol Actions

This mixture contains individual components, including AEBSF, 1,10-Phenanthroline, Pepstatin A, Leupeptin, Bestatin, and E-64. Each component has specific inhibitory properties. AEBSF acts 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. 1,10-Phenanthroline acts against metalloproteases.

Features and Benefits
