Sodium Lauryl Sulfate (CAS 151-21-3) – Wholesale & Research Grade
Sodium dodecyl sulfate is an organic sodium salt that is the sodium salt of dodecyl hydrogen sulfate. It has a role as a detergent and a protein denaturant. It contains a dodecyl sulfate.
Research Context
Sodium Lauryl Sulfate (SLS), also known as Sodium Dodecyl Sulfate or Lauryl Sulfate, is a versatile anionic surfactant widely utilized in various industrial and research applications. Its primary function is to reduce surface tension, making it an essential component in detergents, emulsifiers, and foaming agents.
Research Applications
SLS is extensively employed in biochemical research, particularly in the study of proteins and nucleic acids. It is frequently used in electrophoresis, a technique that separates macromolecules based on their size and charge. This surfactant aids in the denaturation of proteins, allowing for clearer visualization and analysis during polyacrylamide gel electrophoresis (PAGE). Additionally, SLS plays a crucial role in the formulation of drug delivery systems, enhancing the solubility and stability of pharmaceutical compounds.
Mechanism of Action
The mechanism of action of Sodium Lauryl Sulfate revolves around its ability to disrupt lipid membranes. By solubilizing cell membranes, it facilitates the release of intracellular components, which is particularly advantageous in laboratory settings for lysing cells. This property makes SLS a valuable tool in molecular biology for extracting DNA and RNA from biological samples.
Solubility and Storage
Sodium Lauryl Sulfate is soluble in water, with solubility increasing with temperature. For optimal stability, it should be stored in a cool, dry place, away from light and moisture. It is advisable to keep the container tightly closed to prevent contamination and degradation. When preparing solutions, it is essential to use deionized water to maintain purity and avoid unwanted reactions.
Future Research Directions
As research continues to evolve, future studies on Sodium Lauryl Sulfate may focus on its role in nanotechnology and material science, particularly in the development of nanocarriers for targeted drug delivery. Additionally, investigations into its environmental impact and biocompatibility are essential, given its widespread use in consumer products. Understanding these aspects will lead to improved formulations and sustainable practices in various industries.
