3-[(3-Cholamidopropyl)dimethylammonio]-2-hydroxy-1-propanesulfonate

Description:
3-[(3-Cholamidopropyl)dimethylammonio]-2-hydroxy-1-propanesulfonate, commonly referred to as CHAPS, is a zwitterionic detergent widely used in biochemistry and molecular biology. It is characterized by its ability to solubilize membrane proteins while maintaining their functional integrity, making it invaluable in protein purification and analysis. CHAPS has a hydrophilic head group and a hydrophobic tail, which allows it to interact with both polar and nonpolar environments. This amphiphilic nature facilitates the disruption of lipid bilayers, aiding in the extraction of proteins from cellular membranes. CHAPS is known for its mild properties compared to other detergents, minimizing protein denaturation and aggregation. It is soluble in water and exhibits good stability across a range of pH levels. Additionally, CHAPS is often used in applications such as electrophoresis, chromatography, and in the preparation of samples for mass spectrometry. Its unique structure and properties make it a versatile tool in biochemical research and applications.
