Legend Supplementary Figure 6: A) Force extension curves of HTkA in the absence and the presence of 2 mM Mg2+, as indicated. B-F) The histograms of stacking energy, wrapping energy, stiffness, bending angle, and number of bound dimers of HTkA in the absence and the presence of Mg2+ The histograms were fitted with a normal distribution. The mean and standard error of the mean of all fit parameters can be found in Table 2.
 
*** The data was obtained using magnetic tweezers as described in the associated article.

*** Columns show F (Force in pN) and z (Distance in micrometer) of HMfA hypernucleosomes in the absence and presence of 2 mM Mg2+.
