General description

DMSO solution designed for use in the purification of histidine-tagged proteins.

The cocktail contains a mixture of inhibitors that specifically target serine, cysteine, aspartic, and thermolysin-like proteases, and aminopeptidases.

Specificity

Inhibits serine, cysteine, aspartic, and thermolysin-like proteases, and aminopeptidases.

Application

The cocktail has been optimized and tested for isolation of histidine-tagged proteins, with chelating agents omitted for compatibility with IMAC applications.

It is recommended for inhibition of protease activity in 100 mL of cell lysate from 20 g of Escherichia coli or 10 g of baculovirus-infected Spodoptera frugiperda pupal ovary cells.

Features and Benefits

Specifically formulated for histidine-tagged protein purification.

Targets multiple types of proteases, ensuring comprehensive inhibition of protease activity.

Compatibility with IMAC applications due to omission of chelating agents.

Supplied in convenient packaging options.

Components
