Proteases; protease assays and screening systems; and protease and phosphatase inhibitors.

Invasive proteases can contaminate research samples and slow or halt research progress, rendering time-consuming and expensive work useless. Protease inhibitor cocktails are a unique series of enzyme inhibitors that knock out specific proteases to avoid peptide bond hydrolysis and subsequent protein destruction. AG Scientific maintains a large selection of standard inhibitor cocktails in stock, as well as the ability to prepare custom formulations,

Here are four of our more popular Inhibitor products:

• Protease Inhibitor Cocktail III is a specially formulated cocktail of six protease inhibitors with broad specificity for the inhibition of aspartic, cysteine and serine proteases as well as aminopeptidases.
• Protease Inhibitor Cocktail IV specially formulated cocktail of four protease inhibitors with broad specificity for the inhibition of serine, cysteine, aspartic and metallo-proteases.
• Bestatin is an aminopeptidase inhibitor.
• Leupeptin a reversible inhibitor of serine and cysteine proteases. Often used for the inhibition of plasmin, trypsin, papain, kallikrein and cathepsin B.
