| Application: | Anionic detergent |
| Application: | 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. |
