Dr. Gold’s Bacterial Protein Extraction Reagent is a powerful, next-generation solution designed for efficient extraction of expressed proteins from bacterial cells—now reengineered for improved performance and cost-effectiveness. Built on the foundation of our trusted Bacterial Cell Lysis Buffer, this ready-to-use formulation offers enhanced yield and reproducibility without the need for harsh mechanical disruption.

Our proprietary blend of buffering agents and dialyzable, non-denaturing detergents ensures gentle but thorough lysis, preserving native protein structure and activity.

The reagent includes lysozyme, nucleases, and a specially optimized salt solution to promote full membrane disruption and maximize the recovery of soluble proteins.

GoldBio's original formula for Bacterial Cell Lysis Buffer 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. This lysis buffer eliminates viscosity build-up, allowing effective clarification with lower centrifugal forces.

Mammalian Cell Lysis Buffer has been developed for extraction of total soluble proteins from mammalian cultured cells. The Mammalian Cell Lysis Buffer is based on organic buffering agents, which utilizes a mild non-ionic detergent and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. Depending on the application, additional agents such as chelating agents, reducing agents and protease inhibitors may be added into Mammalian Cell Lysis Buffer. Mammalian Cell Lysis Buffer reagent has been tested for use with a wide variety of mammalian cells. Mammalian Cell Lysis Buffer can be used for both suspension as well as adherent cells. The proprietary combination of this reagent provides a simple and versatile method for the extraction of proteins from mammalian cells.

Tissue Cell Lysis Buffer has been developed for extraction of total soluble protein from fresh or frozen animal tissues. Tissue Cell Lysis Buffer is based on an organic buffer, which utilizes a mild non-ionic detergent and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. Depending on the application, additional agents such as chelating agents, reducing agents and protease inhibitors may be added into Tissue Cell Lysis Buffer. Tissue Cell Lysis Buffer reagent has been tested for use with a wide variety of animal tissues.

The Yeast Lysis Buffer Kit is useful for extraction of soluble proteins from yeast cells. It is a proprietary improvement on the Zymolyase® based spheroplast preparation and extraction of soluble proteins from yeast cells.

This kit is provided with an optional protocol to make spheroplast and remove lytic enzyme Zymolyase®, prior to lysis and extraction of yeast proteins. Yeast Lysis Buffer is based on organic buffering agents that utilize a mild non-ionic detergent and a proprietary combination of various salts and agents to enhance extraction and stability of proteins. A ready-to-use Zymolyase® preparation is also provided. Depending on application, additional agents such as reducing agents, chelating agents, and protease inhibitors may be added into Yeast Lysis Buffer.

The Yeast Lysis Buffer has been optimized with Saccharomyces cerevisiae and has been tested on several widely used yeast strains. It also works with both gram-positive and gram-negative bacteria. The proprietary combination of this reagent provides a simple and versatile method of yeast protein extraction. Yeast Lysis Buffer eliminates the need for laborious glass bead lysis of yeast cells.

This kit is suitable for processing 100 x 50 µl yeast cell pellet preparations. Yeast Lysis Buffer is also available separately for further downstream processing.
