Bacterial Protein Extraction Lysis Buffer (with Tris-HCl)

Description

Bacterial Protein Extraction Lysis Buffer (with Tris-HCl) is a specialized bacterial protein extraction buffer designed for efficient disruption of bacterial cells and recovery of recombinant proteins from expression systems such as Escherichia coli. During bacterial protein preparation, incomplete cell disruption, poor protein solubilization, or inefficient separation of soluble proteins and inclusion bodies can reduce downstream purification efficiency. This bacterial lysis buffer provides a reliable extraction environment to help researchers obtain bacterial protein lysates for protein purification, SDS-PAGE analysis, and biochemical studies.

Formulated with Tris-HCl, Triton X-100, and NaCl, this bacterial protein extraction reagent supports efficient cell lysis while maintaining a suitable ionic environment for protein stability. After bacterial disruption, the lysate can be separated into soluble protein fractions and insoluble inclusion body fractions, allowing researchers to select appropriate downstream purification strategies according to protein characteristics.

Bacterial Protein Extraction Lysis Buffer (with Tris-HCl) is suitable for recombinant protein expression workflows, including His-tag protein purification, GST fusion protein preparation, and other bacterial protein production applications requiring efficient extraction of intracellular proteins.

Protocol Overview

Bacterial Protein Extraction Lysis Buffer (with Tris-HCl) is typically used after bacterial culture and cell harvesting.

• Collect bacterial cells by centrifugation after reaching the desired culture density.
• Add appropriate volume of bacterial protein extraction buffer and resuspend the cell pellet thoroughly.
• Disrupt bacterial cells using ultrasonic cell disruption under cold conditions to minimize protein degradation.
• Centrifuge the lysate to separate soluble protein-containing supernatant and insoluble inclusion body fractions.
• Use the collected protein fractions for downstream purification, SDS-PAGE, Western blot, or biochemical analysis.

Optimization of lysis conditions may be required depending on bacterial strain, expression level, and target protein characteristics.
