Size distribution measured by DLS.

(A) Size distribution profile of E7 dimer before addition EDTA. (B) Size distribution profile of E7SOs. (C) Kinetics of E7SOs formation followed by DLS (black circles with error bars), where the initial time correspond to E7 dimer before the addition of EDTA, kinetics followed by Th T fluorescence (black line) and far-UV CD at 216 nm (black circles). The experiments were carried out at the same protein concentration and triggered by the addition of 1.0 mM EDTA.
