Sodio dodecilsulfato (SDS)

SDS is an anionic detergent and wetting agent that is effective in both acid and alkaline solutions.


  • Auto Ignition: 248 °C (powder containing 90% SLS); 447 °C (solution containing 14.8%SLS) (Lit.)
  • Vapor Pressure: Practically zero (Lit.)
  • Aggregation Number: 62
  • Critical Micelle Concentration (CMC): 8.27mM
  • Soluble in water (200 mg/ml - clear, faint yellow solution), and ethanol (0.1 g/10 ml).


Most proteins bind SDS in a ratio of 1.4 grams SDS to 1 gram protein. The charges intrinsic to the protein become insignificant compared to the overall negative charge provided by the bound SDS. The charge to mass ratio is essentially the same for each protein and will migrate in the gel based only on protein size.
An anionic detergent typically used to solubilize and denature proteins for electrophoresis. SDS has also been used in large-scale phenol extraction of RNA to promote the dissociation of protein from nucleic acids when extracting from biological material.
