Figure 12.

Electron microscopy images of F-actin incubated with tauPRD in the presence of NaCl at different concentrations. Conditions were the same as those in Figure 7, except that different concentrations of NaCl were added to the reaction mixtures of F-actin and tauPRD (tau or tauMTBD) as indicated. The bar in each panel represents 200 nm.
