Description

Application

Anionic detergent

SDS may be used:
• in peptide mapping and protein analysis by gel electrophoresis.
• to utilize in designing formulations and its effect on adsorption and micellization parameters.
• in measuring protein-SDS complexes and SDS solution in guanidine hydrochloride using gel chromatography.
• in seperating protein subunits dissociated with SDS using Hydroxylapatite chromatography.

General description

Sodium dodecyl sulfate (SDS) is a detergent suitable to denature proteins. It is a long-chain aliphatic group which has negatively charged sulfate, hence making it amphipathic detergent in nature.
