Abstract. Most analytical electrophoreses of proteins are achieved by separation in polyacrylamide gels under conditions that ensure dissociation of proteins into individual polypeptide subunits and minimize aggregation. Most commonly, the anionic detergent sodium dodecyl sulfate (SDS) is used in combination with a reducing agent (β ...

PMID: 22585476. DOI: 10.1007/978-1-61779-821-4_5. Usually proteins are separated by polyacrylamide gel electrophoresis (PAGE) in the presence of a detergent and under (heat-) denaturing and (non- or) reducing conditions. The most commonly used detergent is sodium dodecyl sulfate (SDS).
The gel is mostly made from polyacrylamide, which is why this type of gel electrophoresis is then referred to as sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). It is also possible to combine dodecyl sulfonic acid with an ammonium ion, resulting in ammonium dodecyl sulfate. In order to increase water solubility, a ...
Sodium Dodecyl Sulfate (SDS) is an alcohol detergent derived from Alcohol Sulfates. Alternatively, it is also known as Sodium Lauryl Sulfate (SLS). SDS is represented by molecular formula C 12 H25 NaO 4S or CH 3= (CH 2)11-O-SO 3-Na + with molecular weight of 288.38 g mol −1. It is commonly used in biochemical research involving
Protein samples to be resolved (e.g., purified protein or cell lysates) SDS stock solution (10% w/v, electrophoresis grade) for resolving and stacking gels. Dissolve 10 g of SDS in 80 mL of H2O, and then add H2O to 100 mL. This stock solution is …

1 Introduction. A first hallmark in protein electrophoresis was the introduction of sodium dodecyl sulfate (SDS) ( 1, 2 ). In the presence of SDS, the individual charge of a protein is no more relevant for its mobility in a polyacrylamide gel. The detergent forms micelles around the protein molecule.
