Descrição geral

Sodium dodecyl sulfate (SDS) is an anionic surfactant with an ability to denature proteins. It has a long-chain aliphatic group with negatively charged sulfate attached. This makes SDS an amphipathic detergent. [1]

Aplicação

Sodium dodecyl sulfate has been used as a:
  • surfactant to evaluate cytochrome c affinity by using surface plasmon resonance[2]
  • surfactant in particle enhanced immunoassays to inhibit aggregation of particles and to enhance single microsphere coupling[3]
  • biofilm-disrupting agent[4]
