Detergent used to plasma membrane
WebCertain detergents can be used to selectively extract and isolate membrane (hydrophobic) proteins from cytosolic (hydrophilic) proteins. For example, solutions of Triton X-114 are homogeneous at 0°C (form a clear micellar solution) but separate into aqueous and detergent phases above 20°C (the cloud point) as micellar aggregates form and the ... WebDetergents are amphipathic molecules. Because of their chemical structure, they form micelles (globular structures) with hydrophobic interiors and polar surfaces. Hydrophobic membrane components can be transferred from membranes to the detergent micelles. Both nonionic detergents and ionic detergents are used.
