Triton® X100

Triton X-100 is a polymerization product of isooctylphenol and ethylene oxide with an average value of 9.5 ethylene oxide units/molecule. It is one of the most frequently used surfactants for the isola¬tion, purification and analysis of membrane components. This surfactant possesses a high solubilization potential whilst in many cases preserving biological properties to a maximum degree. It can be used in place of Nonidet NP-40 (Shell) which is no longer produced.

Triton X-100 is the surfactant of choice for the solubilization and characterization of many enzymes e.g. acetylcholinesterases, protein kinases and adenosinetriphosphatases. It can also be applied to the investigation of mem¬brane proteins like photosystems, ion channels and receptors. Recently, it has frequently been used in combination with other detergents for the isolation and characterization of lipid rafts.

Furthermore, Triton X-100 is used for cell permeabilization, for electrophoretic and chromatographic separations of proteins, in chemiluminescence and fluorescence assays, for some cell culture techniques etc.
