Effect of salt identity on the phase diagram for a globular protein in aqueous electrolyte solution

Article Abstract:

Monte Carlo simulations are used to establish the potential of mean force between two globular proteins in an aqueous electrolyte solution. After fitting this potential to an analytic function, first-order perturbation theory to predict the phase behavior of aqueous lysozyme solutions that contain a specific electrolyte and it shows that interactions between a pair of lysozyme particles become more attractive when the 0.2M electrolyte changes from NaCl to NaI to NaSCN.

Hofmeister effects in pH measurements: Role of added salt and co-ions

Article Abstract:

Measurements of pH with glass electrode that reveal a strong dependence on the ion pair of the background electrolyte and on the salt concentration are presented. It is shown that this effect can be understood once neglected ionic dispersion potentials acting between ions and glass-water interface are taken into account.

Hofmeister effects in enzymatic activity: Weak and strong electrolyte influences on the activity of Candida rugosa lipase

Article Abstract:

The effects of weak and strong electrolytes on the enzymatic activity of Candida rugosa lipase are investigated. It is shown that both buffers and the choice of background electrolyte ion strongly affect the enzymatic activity of Candida rugosa lipase and the effects are dramatic at high salt concentration.
