Figure 3

A plot of the apparent weight average molar mass, Mw,app against concentration, from sedimentation equilibrium. The Mw,app values were not significantly concentration-dependent, meaning that they were not affected by non-ideality. The ideal value was therefore taken as the average (red line), Mw = (4.3 ± 0.2) kDa. The data was analysed with SEDFIT-MSTAR using the M* method to obtain the shown Mw,app values. Rotor speed = 45,000 rpm.
