The Bacterial Cell Lysis Kit has been developed for the extraction of biologically active, soluble proteins and inclusion bodies from bacterial cells. The Bacterial Lysis Buffer is a proprietary improvement on the lysozyme based lysis method, which allows extraction of soluble proteins and concurrent removal of nucleic acids (DNA & RNA) released during cell lysis. The kit’s lysis eliminates viscosity build-up, allowing effective clarification with lower centrifugal forces.

Bacterial Cell Lysis Buffer is based on organic buffering agents andutilizes a mild non-ionic detergent and a proprietary combination ofvarious salts and agents to enhance extraction and stability ofproteins. Depending on the application, additional agents such asreducing agents chelating agent, and protease inhibitors may be addedinto Bacterial Cell Lysis Buffer. This reagent has been tested for usewith several widely used bacteria including E. coli strains. Bacterial Cell Lysis Buffer eliminates the need for laborious mechanical lysis of bacterial cells and removal of DNA/RNA with nuclease treatments. The proprietary combination of this reagent provides a simple and versatile method of bacterial protein extraction and isolation of inclusion bodies.

The Bacterial Cell Lysis Kit (GB-176; 100, 250 or 500 preps) includes a separate tube of modified lysozyme preparation that contains nucleases and results in optimal lysis and minimal contamination. This kit contains all of the reagents needed to perform protein extraction.For extracting soluble proteins, one prep is suitable for extracting approximately 300 mg wet cell pellets for every 1 ml Bacterial Cell Lysis Buffer. When the kits are used for extracting soluble proteins from spheroplasts, one prep is suitable for extracting approximately 90 mg wet cell pellets for every 40 μl Bacterial Suspension Buffer. Bacterial Lysis Buffer is also available separately for further downstream applications.
