| Application: | Anionic detergent |
| Application: | Sodium dodecyl sulfate has been used as a: • surfactant to evaluate cytochrome c affinity by using surface plasmon resonance • surfactant in particle enhanced immunoassays to inhibit aggregation of particles and to enhance single microsphere coupling • biofilm-disrupting agent |
| General description: | 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. |
