Sodium Channels in Planar Lipid Bilayers
Single channel currents of sodium channels purified from rat brain and reconstituted into planar lipid bilayers were recorded . The kinetics of channel gating were investigated in the presence of batrachotoxin to eliminate inactivation and an analysis was conducted on membranes with a single active channel at any given time . Channel opening is favored by depolarization and is strongly voltage ...
متن کاملWater Permeability of Asymmetric Planar Lipid Bilayers
To understand how plasma membranes may limit water flux, we have modeled the apical membrane of MDCK type 1 cells. Previous experiments demonstrated that liposomes designed to mimic the inner and outer leaflet of this membrane exhibited 18-fold lower water permeation for outer leaflet lipids than inner leaflet lipids (Hill, W.G., and M.L. Zeidel. 2000. J. Biol. Chem. 275:30176-30185), confirmin...
متن کاملElectroporation of Planar Lipid Bilayers and Membranes
Strong external electric field can destabilize membranes and induce formation of pores thus increasing membrane permeability. The phenomenon is known as membrane electroporation, sometimes referred to also as dielectric breakdown or electropermeabilization. The structural changes involving rearrangement of the phospholipid bilayer presumably lead to the formation of aqueous pores, which increas...

متن کاملNonlinearities in tilt and layer displacements of planar lipid bilayers.
A novel continuum model is proposed to describe the deformations of a planar lipid bilayer suspended across a circular pore. The model is derived within a new theoretical framework for smectic A liquid crystals in which the usual director n, which defines the average orientation of the molecules, is not constrained to be normal to the layers. The free energy is defined by considering the elasti...
