FIGURE 4.
Dimensionless osmotic compressibility of BLG at pH 5.1 (10 mM buffer) as a function of mass fraction and NaCl concentration: 0 mM (▪); 100 mM (•); 1 M (▴). Solid lines are the equation of state for AHSs calculated assuming apparent protein specific volume of 1.12 ml g−1 and stickiness parameters of 0.11 (NaCl concentration, 0 mM); 0.24 (100 mM); and 1000 (1 M). With a stickiness parameter of 1000 the 1M NaCl line is essentially that for hard spheres.
