Hofmeister series reversal for lysozyme by change in pH and salt concentration: Insights from electrophoretic mobility measurements

Salis, Andrea; Cugia, Francesca; Parsons, Drew; Ninham, Barry; Monduzzi, Maura

Description

Hofmeister series reversal can occur with change in pH, or increase in salt concentration. The phenomena are a challenge for any theory of ion specific effects. Recent theoretical work predicts how a complex interplay between ionic sizes, hydration and dispersion forces explains Hofmeister series reversal. Electrophoretic mobility measurements on lysozyme suspensions reported here are consistent with the theory.
