Figure 3. Dynamic Light Scattering (DLS) to study the influence of DST on the hydrodynamic properties of soluble chromatin, dinucleosomes and trinucleosomes.

The intensity statistics of 10 measurements each are plotted for (A) soluble chromatin (300 µM DNA base), (B) dinucleosomes (300 µM DNA base) and (C) trinucleosomes (300 µM DNA base) in presence of increasing concentration of DST. Error bars indicate standard deviation. Diffusion coefficients calculated from Z_av radii are plotted as a function of DST concentration for (D) soluble chromatin, (E) dinucleosomes, and (F) trinucleosomes. All experiments were performed at 25°C.
