Protein Extraction Reagent

The GenScript Easy BacLysis Protein Extraction Solution facilitates the removal of soluble proteins from E. coli by gently disrupting the bacterial cell wall. This precisely formulated product provides a simple, speedy, low-cost alternative to mechanical methods such as French Press or sonication. The proprietary formulation employs a mixture of non-ionic detergents that perforate the cell wall without denaturing soluble protein. Depending on the particular intended application, additional components, such as lysozyme, protease inhibitors, salts, reducing agents, or chelating agents, may be added to the buffer. The buffer may be used for both soluble protein extraction and inclusion body purification from total bacterial cell lysates.

Key Features:

Easy to Use single-solution format
Rapid cell lysis of recombinant E. coli
Flexible format compatible with small- and large-scale protein extraction
Compatible with soluble and insoluble protein extraction
Purifies inclusion bodies to near-homogenous levels

Applications:

Disruption of bacterial cells for the removal of active proteins
Inclusion body purification

Example:

Protein extraction using competitor A protein extraction reagent and GenScript’s Easy BacLysis Protein Extraction Solution.

1.5 ml cultures of E. coli strain BL21 (DE3) containing pET-28a encoding target protein were harvested by centrifugation and resuspended in 300 μl competitor A protein extraction reagent, or Easy BacLysis Protein Extraction Solution. Samples in lysis reagent were treated according to their respective protocols. Extracts were clarified by centrifugation, then supernatants were removed and insoluble fractions were resuspended in 300 μl distilled water. The supernatant and insoluble fractions were analyzed by SDS-PAGE and Coomassie blue staining.
