ProBlock™ Gold Bacterial 2D Protease Inhibitor Cocktail [100X]
A broad range, 100X concentrated, ready-to-use protease inhibitor cocktail. ProBlock™ Gold Bacterial 2D contains optimized concentrations of various bacterial protease inhibitors, which provide excellent inhibition of protease activities during recombinant protein purification from bacteria. The cocktail contains both reversible and irreversible protease inhibitors to inhibit metallo, serine and cysteine proteases. It also contains specific inhibitors for bacterial proteases, such as
aspartic proteases and aminopeptidases. A 1X concentration of Bacterial ProteaseArrest™ inhibits over 90% of protease activities.
ProBlock™ Gold Bacterial 2D cocktail does not use EDTA as its metalloprotease inhibitor as it would inhibit the activity of proteins that require divalent cations (Ca2+, Mg2+, or Mn2+) for their biological activity. In addition, EDTA would inhibit the purification of proteins using immobilized metal affinity chromatography (IMAC), for example His tagged or CBP tagged proteins. ProBlock™ Gold Bacterial 2Dcocktail is compatible with immobilized metal affinity chromatography.
