Does the Conformation of Adsorbed Fibrinogen
Platelet activation by polymer surfaces is thought to require preliminary adsorption of fibrinogen and perhaps changes in fibrinogen conformation. We measured fibrinogen adsorption by a series of polymers by two methods. using either 125l-labeled fibrinogen or 125l-Iabeled antifibrinogen antibodies. and correlated the results with platelet reactivity (retention and secretion) in columns of bead...
متن کاملAdsorbed Monomer Analog of a Common Polyelectrolyte
The monomer analog of a common water-soluble charged macromolecule shows surface tilt and cooperative adsorption that would be expected for larger surfactant molecules—the small organic ion behaves as an embryonic surfactant. Yet the organic ion competes with inorganic ions (Na, Mg, etc.) for access to the surface, and therefore its tilt increases with the size of the competing coion. Similar o...
متن کاملComputer simulations of catanionic surfactants adsorbed at air/water interfaces.
Structural properties pertaining to the solvation of mixtures of dodecytrimethylammonium/dodecylsulfate adsorbed at water/air interfaces were studied using molecular dynamics techniques. Two different surfactant coverages, both in the submonolayer regime, were considered: an infinite-diluted catanionic pair and an equimolar mixture, at a surface concentration of 78.7 A2/headgroup. The most stab...
متن کاملPolyelectrolyte molecule conformation near a charged surface
-The scaling theory of conformation of a weakly charged polyelectrolyte molecule attached onto a charged surface is developed. It is shown that the long-range interaction between charged monomer units and similary (or oppositely) charged surface provides
متن کاملConformation and order in polyelectrolyte solutions
2014 The scattering factor of polyelectrolyte solutions in the absence of added salt presents a peak at a scattering vector qm which varies like C 1/2. This has been sometimes interpreted in terms of a local orientational order of cylinders. The variation holds however through many concentration regimes, and other explanations in term of correlation holes have been proposed. We evaluate the dif...
