Description

General description

Sodium dodecyl sulfate (SDS) is an amphipathic detergent commonly used for denaturing proteins. SDS has a long-chain aliphatic group, with negatively charged sulfate groups that coat the surface of proteins, causing them to lose their quaternary structure.

Application

Anionic detergent

Sodium dodecyl sulfate has been used:

• in chromatin immunoprecipitation
• in SDS-polyacrylamide gel electrophoresis (SDS-PAGE)
• as a component of radioimmunoprecipitation assay buffer for immunoblotting

Analysis Note

Tested for use in denatured polyacrylamide gel electrophoresis.
