The Electrophoresis grade SDS is tested for suitability as a reagent in electrophoresis. This SDS does not contain any contaminating ions that might impair proper electrophoretic mobility of test samples. SDS is an anionic detergent and wetting agent that is effective in both acid and alkaline solutions. SDS has a wide variety of applications, but is most often used as a protein and lipid solubilization reagent. As a general rule for the solubilization of proteins, SDS should be used at its critical micelle concentration. SDS is also a powerful protein denaturant. The effects of SDS on protein conformation has been published. Comparisons between SDS and other detergents for solubilization of lipids, proteins, and its effect on enzymes activity has been published.
