Description

Application

Détergent anionique

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.

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.
