Sodium dodecyl sulfate (SDS) is an anionic (negatively charged) detergent. It binds to proteins on average every two amino acids along a polypeptide chain. In doing so and in the presence of a reducing agent such as β-mercaptoethanol disulfide bridges within the protein are broken denaturing the molecule into an extended linear form.
