Sodium Lauryl Sulphate is primarily used in molecular biology as a denaturing agent in SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis), a technique essential for analyzing proteins based on their molecular weight. It is also utilized in DNA and RNA extraction protocols, where it helps to lyse cells and solubilize nucleic acids. Beyond molecular biology, SDS is employed in various industries, including cosmetics, pharmaceuticals, and detergents, due to its surfactant properties.
