Description

Application

Sodium dodecyl sulfate was used as a test compound for studying that whether Bacillus amyloliquefaciens KPS46 can induce priming, signaling, protein production as well as systemic protection in soybean (Glycine max L.) against several diseases.

Anionic detergent

Biochem/physiol Actions

Sodium dodecyl sulfate (SDS) is an anionic detergent that can form complexes with protein through hydrophobic interactions. Studies have reported that the hydrodynamic functions of protein-SDS complexes are governed by the length of their polypeptide chains. Thus, SDS-based electrophoretic techniques can separate protein molecules based on their molecular weights. Additionally, SDS can solubilize cell membranes and can extract membrane-bound proteins.
