Enet
vs. pH diagrams for α3Y and the α3FnY proteins. Solid dots represent Enet values obtained by PFV. Grey dots represent Enet collected from α3(3,5)F2Y using the following conditions: 70 μM protein, 20 mM APB, 75 mM KCl; pH adjusted with 1 M NaOH; step potential 0.15 mV, SW pulse amplitude 25 mV, SW frequency 190 Hz, and temperature 25 °C.
