Ações bioquímicas/fisiológicas

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.[2] Additionally, SDS can solubilize cell membranes and can extract membrane-bound proteins.[3]
