Solubilization of isolated central-nervous-system myelin ...
The mechanism for the solubilization of isolated central-nervous-system myelin by sodium dodecyl sulphate was studied in detail. The release of protein and phospholipid to the 100000 g x 1 h supernatant fraction is dependent on the total amount of detergent relative to the amount of membrane present and on the ionic strength of the solubilization system.
Refolding SDS-denatured proteins by the addition of ...
Sodium dodecyl sulfate (SDS) is a highly effective and widely used protein denaturant. We show that certain amphipathic cosolvents such as 2-methyl-2,4-pentanediol (MPD) can protect proteins from SDS denaturation, and in several cases can refold proteins from the SDS-denatured state.

Removal of sodium dodecyl sulfate from proteins
Abstract. Effective removal of sodium dodecyl sulfate from proteins in water or sodium phosphate buffer was achieved by column chromatography using the ion-retardation resin AG11A8. An average recovery of 83% protein was obtained, while 0.1 to 1.4 moles of sodium dodecyl sulfate remained on each mole of protein.
