A-3497 Sodium Lauryl Sulphate
Smart Lab A-3497 Sodium Lauryl Sulphate (SLS), also known as Sodium Dodecyl Sulphate (SDS), is a high-purity anionic surfactant widely used as a laboratory reagent. It is an essential chemical for protein electrophoresis (SDS-PAGE), cell lysis, and a variety of biochemical assays requiring effective denaturation and solubilization of biological molecules.
Description
Description
Sodium Lauryl Sulphate A-3497 is a high-grade Analytical Reagent (AR Grade) supplied by PT. Smart Lab Indonesia. It is presented as a white to off-white crystalline powder or flakes.
Due to its amphiphilic structure—comprising a hydrophobic 12-carbon alkyl chain and a hydrophilic sulphate head group—SLS is highly effective at reducing surface tension and disrupting non-covalent interactions in proteins and lipids. This makes it a critical reagent in molecular biology, biochemistry, and analytical laboratories.
Main Features
Powerful Protein Denaturant
Widely used in molecular biology to denature proteins, converting them into linear chains and imparting a uniform negative charge for accurate size-based separation during SDS-PAGE.
Effective Cell Lysis and Extraction
Acts as a strong detergent for disrupting cell membranes, enabling efficient extraction of DNA, RNA, and intracellular proteins.
Excellent Water Solubility
Highly soluble in water, forming clear solutions with strong foaming and emulsifying properties suitable for laboratory formulations.
High Analytical Purity
As an A-series reagent from Smart Lab, it meets strict analytical purity standards (typically ≥99%), minimizing interference in sensitive biochemical and analytical applications.
Wetting and Emulsifying Agent
Commonly used to enhance the solubility of hydrophobic compounds and to stabilize oil-in-water emulsions in laboratory and research formulations.
Bacteriostatic Activity
Inhibits the growth of many Gram-positive bacteria, making it useful in the preparation of selective culture media and specialized microbiological applications.
