General description

This particular protease inhibitor cocktail omits chelators (e.g., EDTA), to optimize its use for purification of histidine-tagged proteins.1 It contains inhibitors with a broad specificity for serine, cysteine, and acid proteases, and aminopeptidases. The cocktail has been tested on extracts from E. coli and insect cells This cocktail is supplied as a ready-to-use solution using a proprietary non-freezing formulation. ReadyShield PIC0004 is a non-freezing formulation that contains the same inhibitors as is the DMSO based cocktail P8849.

Features and Benefits

  • Does not freeze in storage for quick, convenient use.
  • Tailored for use with Histidine fusion tagged proteins.
  • Suggested as 100 X solution.
  • Reclosable screw-top vials.
  • Can be stored in cooler for approx. 1 month or room temperature for a week.

Preparation Note

The recommended dilution of the cocktail in the biological extract is 1 ml of the cocktail per 100 ml of lysate from 20 g (wet weight) of E. coli cells or 10 g (wet weight) of baculovirus-infected insect (Spodoptera frugiperda) cells.
