Table II.

LLPS critical temperatures, T_c, of eight human IgGs, and the slope of PEG concentration dependency of T_ph, ${\left(\partial T_{\mathrm{ph}}/\partial c_2\right)}_{c_1}$, at fixed protein concentration 98 mg/ml. The deviations of T_c and ${\left(\partial T_{\mathrm{ph}}/\partial c_2\right)}_{c_1}$ are the errors of linear fitting of T_ph versus PEG concentration c₂.
