General description
Sodium dodecyl sulfate (SDS) is an organic sodium salt used as both a detergent and a protein denaturant in biochemical research. Its unique structure includes a long-chain aliphatic group with a negatively charged sulfate, making it an effective agent for denaturing proteins. This property is especially valuable in electrophoresis, a technique used to separate and analyze macromolecules like proteins. SDS, with its negative charge, interacts with proteins and lipids to create micellar structures, aiding in solubilizing and stabilizing these biomolecules.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product is used as a surfactant to enhance catalysis. Click here for more information.
Application
Anionic detergent
Sodium dodecyl sulfate (SDS) has been used:
- as a negatively charged surfactant to study its effects on filtration flux and membrane fouling during the microfiltration of the surfactant-stabilized oil emulsion
- as a component of plant extraction buffer, and transferring buffer for western blot
- as a component of 5× Laemmli sample buffer (5× LB) and 10× SDS running buffer for sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblot
Biochem/physiol Actions
Sodium dodecyl sulfate (SDS) effectively binds to the positively charged and the hydrophobic residues of proteins via sulfate groups and alkyl chains. It functions as a vital detergent in the domain of structural biology and protein folding/unfolding studies. SDS can stimulate the creation of α-helices in a protein structure. It has the ability to promote cooperative unfolding in several proteins including bovine serum albumin (BSA), β-lactoglobulin, α-lactalbumin, and hen egg-white lysozyme structures at elevated concentrations.
