Ionic strength dependence of protein-polyelectrolyte interactions.
The effect of univalent electrolyte concentration on protein-polyelectrolyte complex formation has been measured by frontal analysis continuous capillary electrophoresis (FACCE) and turbidimetry for the interaction of bovine serum albumin (BSA) with a synthetic hydrophobically modified polyacid, for BSA with (porcine mucosal) heparin (Hp), a highly charged polyanion, and for Hp and insulin. All...
متن کاملDivalent-anion salt effects in polyelectrolyte multilayer depositions.
We systematically investigate the effects of divalent anions on the assembly of polyelectrolyte multilayers by fabricating polystyrene sulfonate (PSS)/polyallylamine hydrochloride (PAH) multilayer films from aqueous solutions containing SO(4)(2-), HPO(4)(2-), or organic dicarboxylate dianions. The chosen concentrations of these anions (i.e., ≤0.05 M) allow us to isolate their effects on the ass...
متن کاملIon multivalence and like-charge polyelectrolyte attraction.
It is known empirically that multivalent ions generate attractions between like-charged polyelectrolytes, with different valence requirements for different systems. How multivalent must an ion be before it can condense a given polyelectrolyte? Using charge-tunable M13 virus rods and a family of artificial homologous "dumbbell" divalent ions of different sizes, we have constructed a multivalent ...
متن کاملCharge transport in redox polyelectrolyte multilayer films: the dramatic effects of outmost layer and solution ionic strength.
The redox switching kinetics, that is, charge transfer and transport in layer-by-layer-deposited electroactive polyelectrolyte multilayers is systematically studied with variable-scan-rate cyclic voltammetry. The experiments are performed with films finished in the redox polycation (an osmium pyridine-bipyridine derivatized polyallylamine, PAH-Os) and the polyanion (polyvinyl sulfonate, PVS), i...
متن کاملDependence of Polyelectrolyte Apparent Persistence Lengths, Viscosity, and Diffusion on Ionic Strength and Linear Charge Density
Apparent electrostatic persistence lengths (i.e., those found by substituting the perturbed for the unperturbed mean-square gyration radius in the wormlike chain theory) obtained from static light scattering for variably ionized acrylamideJsodium acrylate copolymers varied approximately as the inverse square root of the ionic strength, C,, and linearly with fractional ionization. While this doe...
