Adsorption of divalent cations to bilayer membranes containing phosphatidylserine
The Stern equation, a combination of the Langmuir adsorption isotherm, the Boltzmann relation, and the Grahame equation from the theory of the diffuse double layer, provides a simple theoretical framework for describing the adsorption of charged molecules to surfaces. The ability of this equation to describe the adsorption of divalent cations to membranes containing brain phosphatidylserine (PS...
متن کاملInstability and Periodic Deformation in Bilayer Membranes Induced by Freezing
The instability and periodic deformation of bilayer membranes during freezing processes are studied as a function of the difference of the shape energy between the high and the low temperature membrane states. It is shown that there exists a threshold stability condition, bellow which a planar configuration will be deformed. Among the deformed shapes, the periodic curved square textures are sho...
متن کاملTethered and Polymer Supported Bilayer Lipid Membranes: Structure and Function
Solid supported bilayer lipid membranes are model systems to mimic natural cell membranes in order to understand structural and functional properties of such systems. The use of a model system allows for the use of a wide variety of analytical tools including atomic force microscopy, impedance spectroscopy, neutron reflectometry, and surface plasmon resonance spectroscopy. Among the large numbe...
متن کامل-heparin hydrogels catheter membranes
Poly(vinyl alcohol)-heparin hydrogels with varying water content were synthesized for use as sensor catheter membranes. Films were cast from aqueous mixtures of poly(vinyl alcohol) (PVA), a photosensitive cross-linker p-diazonium diphenyl amine polymer (PA), glutaraldehyde (GA) and heparin. After drying, the films were cross-linked by successive UV irradiation and heat treatment. To get an indi...
متن کاملRhodopsin in bilayer membranes.
Visual excitation is initiated with the absorption of light by the membrane-bound visual pigment rhodopsin. The effect of light on rhodopsin is now quite generally believed to be a photoisomerization of the chromophore, retinaldehyde, from the 1 1-cis to the all-rransconliguration(Hubbard & Kropf, 1957; Wald, 1968). This is followed by changes in the shape of the protein, and these lead to cond...
