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.[23]

Application

SDS may be used:
  • in peptide mapping and protein analysis by gel electrophoresis.
[21]
  • to utilize in designing formulations and its effect on adsorption and micellization parameters.
  • [27]
  • in measuring protein-SDS complexes and SDS solution in guanidine hydrochloride using gel chromatography.
  • [28]
  • in seperating protein subunits dissociated with SDS using Hydroxylapatite chromatography.
  • [29]
    Anionic detergent
