Description Bacterial Protein Extraction Lysis Buffer (with PBS) is a PBS-based bacterial protein extraction buffer designed for efficient disruption of bacterial cells and preparation of protein lysates from expression systems such as Escherichia coli. During recombinant protein production, incomplete bacterial cell lysis, unstable extraction conditions, or poor separation of soluble proteins and inclusion bodies can reduce protein recovery and affect downstream purification and analysis. This bacterial cell lysis buffer provides a stable phosphate-buffered environment to help researchers obtain reliable bacterial protein extracts. Formulated with PBS (phosphate buffered saline), this bacterial protein extraction reagent maintains a suitable ionic environment and pH stability during bacterial protein preparation. After cell disruption, the lysate can be separated into soluble protein fractions and insoluble inclusion body fractions, supporting recombinant protein purification workflows, SDS-PAGE analysis, and protein expression studies. Bacterial Protein Extraction Lysis Buffer (with PBS) is suitable for routine bacterial protein extraction applications, especially for researchers working with E. coli expression systems who require a convenient lysis solution for soluble protein preparation and inclusion body recovery.

Protocol Overview Bacterial Protein Extraction Lysis Buffer (with PBS) is commonly used with mechanical disruption methods such as sonication for efficient bacterial protein extraction. Collect bacterial cells by centrifugation after cultivation. Add appropriate volume of bacterial protein extraction buffer and resuspend the cell pellet completely. Perform cell disruption on ice using sonication or other suitable mechanical methods. Centrifuge the lysate to separate soluble protein fractions and inclusion body fractions. Collect the supernatant or pellet according to downstream protein purification requirements. Keeping samples cold during bacterial protein extraction is recommended to minimize protein degradation and maintain sample quality.
