Phase separation of integral membrane proteins in Triton X-114 solution.
A solution of the nonionic detergent Triton X-114 is homogeneous at 0 degrees C but separates in an aqueous phase and a detergent phase above 20 degrees C. The extent of this detergent phase separation increases with the temperature and is sensitive to the presence of other surfactants. The partition of proteins during phase separation in solutions of Triton X-114 is investigated. Hydrophilic p...
متن کاملRemoval of endotoxin from protein solutions by phase separation using Triton X-114.
Endotoxin contamination of protein solutions was reduced by a phase separation technique using the detergent, Triton X-114. Protein solutions containing endotoxin were treated with Triton X-114 on ice. The solution was then warmed to 37 degrees C, whereupon two phases formed. The Triton X-114 phase, containing the endotoxin, was precipitated by centrifugation. The first cycle of phase separatio...
متن کاملAnomalous interaction of the acetylcholine receptor protein with the nonionic detergent Triton X-114.
Integral membrane proteins that form water-filled channels through membranes often exist as aggregates of similar or identical subunits spanning the membrane. It has been suggested that the insertion into the membrane of the channel-forming domains of the subunits may impart unusual structural features to the membrane-intercalated portions of the protein. To test this proposal, we have investig...
متن کاملSpectroscopic Studies of Triton X-114 and Quercetin/Rutin Solutions
Flavonoids belong to a large group of natural polyphenol compounds and have a broad spectrum of pharmacological activities. Many natural flavonoids are characterized by extremely low solubility in aqueous media and body fluids. To improve the solubility of drugs, various methods were developed and are used in pharmaceutics: solubilization, preparation of solid disperse systems with soluble and ...
متن کاملNovel procedure for extraction of a latent grape polyphenoloxidase using temperature-induced phase separation in triton x-114.
Polyphenoloxidase from grape berries is extracted only by nonionic detergents with a hydrophilic-lipophilic balance between 12.4 and 13.5. The enzyme was partially purified in latent form, free of phenolics and chlorophylls, by using temperature phase partitioning in a solution of Triton X-114. This method permits the purification of the enzyme with the same fold purification as the commonly us...
