The DLS data shown in Figure 5b was obtained using the 146 bp α-satellite DNA derivative, rather than the 145 bp 601 DNA fragment.

Under the subheading ‘Solution structure of the H2A.B nucleosome’:

“In this analysis, we used the 145 bp 601 DNA fragment, which reportedly forms a stably positioned nucleosome3. Consistent with previous electron and atomic force microscopic analyses29, the mean particle size of the H2A.B octasome with the 145 bp 601 DNA fragment was clearly larger than that of the canonical H2A octasome (Fig. 5a and b).’’
