^a${\text{Γ}}_{eff}$ was computed using Eq. 3b from $G_{eq}$ and ${\epsilon }_0=q{V}_0/2$ and number of molecules, $N=\frac{1E14{\left[nm/cm\right]}^2}{footprint\left[n{m}^2\right]},$with protein's footprint of 80, 140, and 60 nm² for bR, PS-I, and ferritin, respectively. These values are based on protein's diameter and include a factor of 2 for circular surface filling; the bR is further multiplied by 2 to account for surrounding OTG matrix.

^btip-EGaIn shows two values for Ferritin: the upper one was measured by UoG (as were the other two proteins) and the lower one by WIS.
