Anion- and protein-induced secondary structure in acid-unfolded SNase (pH 2.5). (A) the effect of increasing Na2SO4 at low protein concentration (0.15 mg/ml). (B) The effect of increasing protein concentration at fixed sulfate (250 mM), leading to association. All measurements were carried out at 23°C.
