Sodium dodecyl sulfate (Cat No.: M068992), also known as sodium lauryl sulfate, is an anionic surfactant composed of a 12-carbon hydrophobic tail and a sulfate hydrophilic head. This white, water-soluble powder is widely used in detergents, personal care products, and laboratory applications. In molecular biology, SDS is essential for protein denaturation in SDS-PAGE electrophoresis. Its strong emulsifying and foaming properties make it effective in cleaning formulations. SDS also disrupts lipid membranes, enabling its use in cell lysis and membrane protein extraction.
