Cell Lysis Buffer
Cell Lysis Buffer — A solution containing detergents and protease inhibitors used to break open cells and release intracellular contents for peptide and protein analysis.
What Is Cell Lysis Buffer?
Cell lysis buffer is a solution used to break open cells and release their contents for peptide extraction and analysis. Lysis buffer composition must be optimized to efficiently disrupt cells while preserving target peptide integrity, preventing proteolytic degradation, and maintaining PTM status.
Key Components
- Detergent: Triton X-100 (mild, non-denaturing), SDS (strong, denaturing), NP-40 (membrane solubilization)
- Protease inhibitors: PMSF, aprotinin, leupeptin, pepstatin A cocktail prevents peptide degradation
- Phosphatase inhibitors: Sodium orthovanadate, sodium fluoride preserve phosphopeptide modifications
- Buffer: Tris or HEPES pH 7.4 with 150 mM NaCl
