Hydration and stability of sulfatide-containing phosphatidylethanolamine small unilamellar vesicles.
The effect of sulfatide on membrane hydration of 1, 2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE) small unilamellar vesicles (SUVs) was investigated using steady-state and time-resolved fluorescence spectroscopy. The degree of hydration in the headgroup region of the bilayer lipids was assessed with the fluorescence lifetime of N-(5-dimethylaminonaphthalene-1-sulfonyl)dipalmitoylphosphatid...
متن کاملCa2+-induced fusion of sulfatide-containing phosphatidylethanolamine small unilamellar vesicles.
The fusogenic properties of sulfatide-containing 1,2-dioleoyl-3-sn -phosphatidylethanolamine (DOPE) small unilamellar vesicles (SUVs) in the presence of CaCl2 were studied by mixing membrane lipids based on an assay of fluorescence resonance energy transfer (FRET). Fusion of the vesicles was also confirmed by mixing aqueous contents with the Tb/dipicolinate (DPA) assay. The half-times of lipid ...

متن کاملDeformability of multilamellar vesicles.
Although a free unilamellar vesicle has zero or almost zero genuine surface tension, the multilamellar vesicle ("onion") exhibits a nonzero effective surface tension sigma(eff). The expression for sigma(eff) used in the literature is sigma(eff) approximately square root of kappaB/d(0), where B is the interaction modulus between the vesicle bilayers, d(0) the repeating distance between the bilay...
متن کاملSmall-angle scattering model for multilamellar vesicles.
A small-angle neutron-x-ray-light-scattering model for multilamellar vesicles is developed on the basis of a simple geometry. N spherical shells with radii of an arithmetic series are allowed for displacements DeltaR which are limited by DeltaR<R/N due to sterical reasons, with R being the radius of the vesicle. The model shows many properties over a large Q range which include a Guinier region...
