Proteins in mixed solvents: A molecular-level perspective
Article Abstract:
A statistical mechanical approach for quantifying the thermodynamic properties of proteins in mixed solvents is presented. It is found that the observed differences in the binding of glycerol and urea to RNase T1 and A are predominantly a consequence of density differences in the first coordination shell of the protein with the cosolvents, but the second solvation shell also contributes to the overall binding coefficients.

Proteins of aqueous solutions of polyelectrolytes and surfactants of opposite charge: surface tension, surface rheology, and electrical briefringence studies
Article Abstract:
The dynamic behavior of both surface and bulk of mixed solutions of surfactants and polymers of opposite electrical charges are described. It was found that in the bulk, the surfactant not only screens the polymer charges but is likely to start binding to the polymer chains.

Nonuniform charge effects in protein-protein interactions
Article Abstract:
Calculations are carried out for determining the electrostatic interaction energy for two protein molecules, as a function of separation and orientation. The results indicate that the mechanisms of charge heterogeneity and charge fluctuations act in a complementary way.
