Figure 5. Comparison to 1D Diffusion coefficients of other proteins.

Comparison of the 1D diffusion coefficients reported for various proteins^{11; 33; 34; 35} (black disc) on dsDNA and our measurement of the apparent diffusion coefficient of SSB on ssDNA (red circle). Previously reported diffusion coefficients of SSB¹¹ (black circle) are the smallest of all. (These were converted from units of nt²s⁻¹ to μm²s⁻¹, for comparison using the conversion factor at 2.1 pN. The higher of the two was an extrapolation to 37 °C, while the lower was measured at 4 °C.¹¹)
