AG Scientific: A Leader in 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.

AG Scientific delivers quality assured reagents directly to scientists, from small-scale to bulk orders. AG is a leader in the bulk supply of Inhibitor cocktails and is an OEM packer for companies worldwide. Allow us to provide custom product packaging or pack in multiple product forms for you. We offer “just in time” delivery, private labeling, and custom formulations for specific research needs.
