Measurement of the binding of proteins to polyelectrolytes by frontal analysis continuous capillary electrophoresis.
We have developed a novel technique, frontal analysis continuous capillary electrophoresis (FACCE), to study the binding of proteins to polyelectrolytes. Compared with existing electrophoresis methods such as conventional frontal analysis and the Hummel-Dreyer method, FACCE offers enhanced lower detection limits and is free from effects due to slow binding kinetics, thus making it suitable for ...
متن کاملMolecular dynamics simulations of electrophoresis of polyelectrolytes in nano confining cylindrical geometries.
We consider molecular dynamics simulations of the electrophoretic motion of charged polymers in straight cylinders and cylinders with a periodic variation (or modulation) of the diameter. The electric field is always orientated along the axis of the cylinders, and it does not change direction. The fluid is modeled explicitly, also the co-ions, counterions, and the charged polymer monomers. In s...
متن کاملCharging of weak polyelectrolytes
Michal Borkovec, Ger J. M. Koper Email. [email protected], [email protected] September 15, 2013 Direct link www.colloid.ch/polyelectrolytes In aqueous solutions, bases bind protons, while acids dissociate them. For weak acids and bases, these protonation reactions occur in the intermediate pH range. Dealing with monoprotic or diprotic acids and bases, the corresponding binding isoth...
متن کاملCharge Inversion Effects in Electrophoresis of Polyelectrolytes in the Presence of Multivalent Counterions and Transversal Electric Fields
By molecular dynamics simulations we investigate the transport of charged polymers in confinement, under externally applied electric fields, in straight cylinders of uniform diameter and in the presence of monovalent or multivalent counterions. The applied electric field has two components; a longitudinal component along the axis of the cylinder and a transversal component perpendicular to the ...
متن کاملAdsorption of Polyelectrolytes on Mica
‘‘Adsorption of Polyelectrolytes on Mica’’ sounds like a very specific title and it may be difficult to envision, upon first reflection, why mica deserves a separate chapter in the study of adsorption of polymers on solid substrates. What makes mica such a special substrate? What are the driving forces involved in the adsorption of macromolecules on mica? What mechanisms participate in the adso...
