Order parameters and areas in fluid-phase oriented lipid membranes using wide angle X-ray scattering.
We used wide angle x-ray scattering (WAXS) from stacks of oriented lipid bilayers to measure chain orientational order parameters and lipid areas in model membranes consisting of mixtures of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)/cholesterol and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)/cholesterol in fluid phases. The addition of 40% cholesterol to either DOPC or DPPC changes...
متن کاملLateral order in gel, subgel and crystalline phases of lipid membranes: wide-angle X-ray scattering.
The chain packing in ordered phases of lipid bilayers can be classified according to wide-angle X-ray diffraction (WAXS). For triclinic (T(‖)) and monoclinic (M(‖)) packing in crystalline L(c) phases, the wide-angle reflections index on an oblique lattice with spacings s(10)≠s(01)≠s(11), and each chain has four nearest neighbours. For orthorhombic (O(⊥)) packing in L(c) phases, and the rotation...
متن کاملTilt-Dependent Analysis of Diffuse X-ray Scattering from Oriented Stacks of Fluid Phase Lipid Bilayers
Recent simulations have indicated that the traditional Helfrich-Canham model for topographical fluctuations in fluid phase biomembranes should be enriched to include molecular tilt. Experimental evidence supporting the aforementioned enrichment is reported. The current work is a tilt-dependent analysis of the X-ray scattering from oriented stacks of fluid phase lipid bilayers. By analyzing seve...
متن کاملInterpretation of the Small-Angle X-ray Scattering from Swollen and Oriented Perfluorinated Ionomer Membranes
Small-angle X-ray scattering (SAXS) and bulk volumetric measurements were performed on the perfluorinated ionomer membrane “Nafion”. The swelling experiments were conducted using controlled environments of different relative humidities. The membranes were oriented using uniaxial draw, both before and after conversion of the precursor material, as well as both sequential and simultaneous biaxial...
متن کاملSimultaneous measurements of small angle x-ray scattering, wide angle x-ray scattering, and dielectric spectroscopy during crystallization of polymers
A novel experimental setup is described which allows one to obtain detailed information on structural and dynamical changes in polymers during crystallization. This technique includes simultaneous measurements of small angle-wide angle x-ray scattering and dielectric spectroscopy ~SWD!. The capabilities of the technique have been probed by following in real time the crystallization process of a...
