Description Protease Inhibitor Cocktail for plant cell and tissue extracts, DMSO solution
form DMSO solution
MDM Code P9599-5ML
Material Number P9599
Business Unit 687
CAS Number 0



Optimized and tested for use with plant tissue and cell extracts. Specific testing was done on plant seedling extracts from pea, bean, wheat, tobacco, and Arabidopsis, as well as leaf and root extracts from pea, wheat and tobacco.

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.


The cocktail should be stored at -20°C, where it will retain stability for two years.

Preparation Note

This product is supplied as a clear, faint pink solution in DMSO. One mL of solution is recommended for inhibition of protease activity in 100 mL of cell lysate from 30 g of various plant tissues or 10 g of baculovirus-infected cells. Extracts of plant seedlings from pea, bean, wheat, tobacco, and Arabidopsis have been tested. The roots of these plants have also been successfully tested.


One mL is recommended for the inhibition of proteases extracted from 30 g of plant tissue in a total volume of 100 ml.


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