Sodium dodecyl sulfate (SDS) or sodium lauryl sulfate (SLS), sometimes written sodium laurilsulfate, is an organic compound with the formula CH 3 (CH 2) 11 OSO 3 Na and structure H 3 C−(CH 2) 11 −O−S(=O) 2 −O − Na +. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12 ...
Proteins of the erythrocyte membrane separated by SDS-PAGE according to their molecular masses. SDS-PAGE (sodium dodecyl sulfate–polyacrylamide gel electrophoresis) is a discontinuous electrophoretic system developed by Ulrich K. Laemmli which is commonly used as a method to separate proteins with molecular masses between 5 and 250 kDa.
Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is a method of separating molecules based on the difference of their molecular weight. At the pH at which gel electrophoresis is carried out the SDS molecules are negatively charged and bind to proteins in a set ratio, approximately one molecule of SDS for every 2 amino acids.
Sodium Dodecyl Sulfate, a common anionic surfactant. The head group classification of a surfactant is determined by the head group ion type. Ionic surfactants derive their amphiphilicity from a charged hydrophilic head group and tend to be small, low molecular weight molecules.
Sodium dodecyl polyoxyethylene sulfate ... by n is specified in the name, for example laureth-2 sulfate. ... 3 sulfate is the most common one in commercial products. ...
Sodium lauryl sulfate → Sodium dodecyl sulfate — "Sodium dodecyl sulfate" (SDS) is far more common. I do not think I have ever heard it called "sodium lauryl sulfate" until I looked here. Is there a particular reason a less common name is used? Thanks! Multivariable 08:58, 14 March 2011 (UTC)
Dodecanol / ˈ d oʊ ˈ d ɛ k ɑː n ɒ l /, or lauryl alcohol, is an organic compound produced industrially from palm kernel oil or coconut oil.It is a fatty alcohol. Sulfate esters of lauryl alcohol, especially sodium lauryl sulfate, are very widely used as surfactants.
Nucleic acids are often denatured by including urea in the buffer, while proteins are denatured using sodium dodecyl sulfate, usually as part of the SDS-PAGE process. For full denaturation of proteins, it is also necessary to reduce the covalent disulfide bonds that stabilize their tertiary and quaternary structure , a method called reducing PAGE.
