Sodium dodecyl sulfate - Wikipedia

Removal of sodium dodecyl sulfate from proteins is difficult, but can be achieved by adding nine volumes of acetone or methanol, holding at −20°C for 1 h, and centrifuging at 13000 g for 10 min. The SDS will remain in solution. Alternatively, the protein may be precipitated with methanol/chloroform (Wessel and Flügge, 1984).
