General description
Beyond protein analysis, SDS also finds applications in the electrophoretic separation of lipids, enabling the study and characterization of these important cellular components. Additionally, SDS is employed in various hybridization and molecular biology techniques, demonstrating its versatility across a range of research areas. SDS′s effectiveness in both ionic and anionic conditions further expands its utility, allowing it to adapt to diverse experimental setups and requirements. Its ability to unravel proteins by binding to peptide chains and imparting a negative charge effectively eliminates protein shape as a factor for gel separation, ensuring accurate protein size determination.
Application
- in chromatin immunoprecipitation
- in SDS-polyacrylamide gel electrophoresis (SDS-PAGE)
- as a component of radioimmunoprecipitation assay buffer for immunoblotting
Features and Benefits
- Highly versatile surfactant for your molecular biology and biochemical research
