The serotonin(1A) (5-HT(1A)) receptor is an important member of the superfamily of seven transmembrane domain G-protein-coupled receptors. We report here that solubilization of the hippocampal 5-HT(1A) receptor by the zwitterionic detergent CHAPS is accompanied by loss of membrane cholesterol which results in a reduction in specific agonist binding activity and extent of G-protein coupling. Imp...
The influence of various concentrations of 15 detergents at different temperatures on the fluidity of membranes was analysed by fluorescence anisotropy of inserted 1,6-diphenyl-1,3,5hexatriene in rat cortical and Sf9 cell membranes. Comparison of the obtained data with the abilities of the detergents to solubilize muscarinic receptor subtypes indicated that not only the fluidity of the micelles...
The extraction of Terbium (III)from aqueous nitrate solutions with a supported liquid membrane was investigated using a mixture of di-(2-ethylhexyl phosphoric acid (D2EHPA) and tri-octyl phosphine oxide (TOPO) with a molar ratio 1/0.4. The Hydrophobic Polyvinylidene Fluoride (PVDF) membrane was used as solid support. The sorption process followed pseudo-second-o...
A model system for selective solubilization and fast separation of proteins from the rat liver membrane fraction and purified rat liver plasma membranes for their further proteomic analysis is presented. For selective solubilization, high-pH solutions and a concentrated urea solution, combined with different detergents, are used. After extraction, proteins are separated by anion-exchange chroma...
Salinarum halorhodopsin (HsHR), a light-driven chloride ion pump of haloarchaeon Halobacterium salinarum, was heterologously expressed in Escherichia coli. The expressed HsHR had no color in the E. coli membrane, but turned purple after solubilization in the presence of all-trans retinal. This colored HsHR was purified by Ni-chelate chromatography in a yield of 3-4 mg per liter culture. The pur...
