Paper Abstract

Static and dynamic light scattering are used to measure molecular parameters of γ-globulin in solutions in the presence of sodium and potassium ions. Intermolecular interactions coefficients and molecular masses of scattering particles in the protein water solutions were determined as a function of pH and ioning strength by static light scattering. In the proteins solutions containing Na+, molecular mass of scattering particles is constant, but in the case of proteins solutions containing K+ ions molecular mass of scattering particles increases in vicinity of isoelectric points of proteins Translational diffusion coefficient dependence as a function of pH and concentration of components was obtained in γ-globulin solutions by using photon correlation spectroscopy.
