BugBuster® Protein Extraction Reagent

BugBuster® Protein Extraction Reagent is formulated to gently disrupt the cell wall of E. coli and liberate soluble proteins. It provides a simple, rapid, low-cost alternative to mechanical methods such as French press or sonication for releasing expressed target protein in preparation for purification or other applications. The reagent is available in a variety of configurations.

Common Features:

  • Simple, rapid, low-cost alternative to mechanical methods (i.e., French Press and sonication)
  • Capable of cell wall perforation without denaturing soluble protein
  • Fully compatible with the affinity supports such as Novagen's GST•Bind™, His•Bind®, and S•Tag™ Resins, and other chromatography matrices
  • Compatible with Benzonase® Nuclease for viscosity reduction
  • Extraction enhanced by addition of small amount of lysozyme
  • Compatible with Protease Inhibitor Cocktails
  • Useful for the preparation of high purity inclusion bodies in instances where expressed proteins are insoluble
  • Reagent is available in a variety of configuration
