Diffusion of spheres in isotropic and nematic networks of rods: Electrostatic interactions and hydrodynamic screening

“…35 for low apoferritin concentrations and is lower than the values reported in Refs. V B, the surface charge Z c of apoferritin is not precisely known.…”

Determination of the concentration dependence of polyelectrolyte diffusion coefficients by application of the Boltzmann gradient method

“…Gapinski et al have performed experiments with apoferritin suggesting c x p ≈ 10 g/l in a 10 −3 M salt solution [16]. Taking M ≈ 450,000 g/mol [19] into account, this yields a molar concentration of 2.2 × 10 −5 M. This agrees well with our value for labeled BSA. Apoferritin experiments in a 10 −4 and a 10 −5 M salt solution in fact show that c x p decreases with decreasing salt concentration.…”

Electrostatically PEGylated DNA enables salt-free hybridization in water

“…The perfect match of the peak positions for both, single-stranded and hybridized DNA-PEG complexes at a particular concentration substantiates the presence of same number of particles per volume (N/V factor mentioned above) in the complex solutions, as the position of such peaks is reported to depend on the concentration of polyions in salt-free and at very low ionic strength aqueous solutions. [60][61][62][63] Remarkable shis in the peak positions with increase in the concentrations of ss22-PEG350 (Fig. S27a †) and ds22-PEG350 ( Fig.…”
