Salt- and LH-dependent folding of 12-nucleosome chromatin fibers. (A) Sedimentation coefficients of chromatin fibers with NRL = 209 bp, with and without LHs, and with 25, 50, 75, and 100 mM NaCl. Green (with LHs) and red (without LHs). Dashed lines represent experimental data taken from (64), and squares with error bars show average and standard deviation obtained from BD. (B) Fiber configurations with and without LHs at 25 and 100 mM NaCl. To see this figure in color, go online.
