Sodium dodécyle sulfate (SDS)

SDS is an anionic detergent and wetting agent that is effective in both acid and alkaline solutions.
Used to solubilize and denature proteins for denaturing-PAGE. Most proteins bind SDS in a ratio of 1.4 g SDS per gram of 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 their size.
