SDS (20% Solution) (CAS 151-21-3)

SDS (20% Solution), also known as sodium dodecyl sulfate or sodium lauryl sulfate, is a potent anionic surfactant widely utilized in biochemical and molecular biology research. This compound consists of a hydrophobic dodecyl chain attached to a hydrophilic sulfate group, rendering it amphipathic and capable of disrupting the structure of proteins and lipids. SDS (20% Solution) finds extensive application in various laboratory techniques, primarily in protein biochemistry and nucleic acid analysis. One of its prominent roles is in the denaturation of proteins, where it unfolds and solubilizes them by disrupting non-covalent interactions such as hydrogen bonds and hydrophobic interactions. This property is crucial in techniques like SDS-PAGE (polyacrylamide gel electrophoresis), where proteins are separated based on their molecular weight. Additionally, SDS is an essential component of many cell lysis buffers, where its detergent action aids in the disruption of cell membranes, releasing cellular components for downstream analysis. It is also commonly used in DNA and RNA extraction protocols to solubilize cellular membranes and proteins, facilitating the isolation of nucleic acids. Moreover, SDS (20% Solution) is utilized in various molecular biology techniques such as Western blotting, immunoprecipitation, and protein purification, where its ability to disrupt protein-protein and protein-lipid interactions is instrumental in achieving accurate results. Research on SDS continues to explore its applications in novel methodologies and its interactions with biological molecules, contributing to advancements in fields ranging from structural biology to drug discovery. Its well-characterized properties and versatile applications make SDS a cornerstone reagent in biochemical research, indispensable for the study of cellular processes and biomolecular interactions.
