Why pH titration in lysozyme suspensions follow a Hofmeister series

Bostrom, Mathias Anders; Ninham, Barry


We present theoretical results that provide new insights into the Hofmeister effects observed in protein suspensions. With a buffered solution at a supposedly fixed pH, measurements of that pH with glass electrodes in protein suspensions depend strongly on both ionic species and concentration of background salt and protein. The observed Hofmeister series cannot be explained with standard electrostatic theories. While purely electrostatic limiting laws can be used to obtain partial understanding...[Show more]
