From: Elucidating the mechanism of the considerable mechanical stiffening of DNA induced by the couple Zn2+/Calix[4]arene-1,3-O-diphosphorous acid

Figure 3

Mechanical measurement of DNA stiffness (red diamonds, left scale) and DNA viscous losses (blue squares, right scale) as a function of (a) Zn2+ and (b) C4diP concentration. Plate (c) shows real time measurements of DNA stiffness (red) and viscous losses (blue) after consecutive injections of Zn2+, C4diP and Histidine (Solution changes are shown between arrows). The real change for Zn2+ alone is shown in the inset.
