MSDs of probe spheres from particle-tracking microrheology measurements on CTF solutions without Ca2+ at different concentrations. The solid line is the predicted MSD for beads 0.489 μm in diameter in water at 25°C using the Stokes-Einstein equation (D = kT/6πηrh, where kT is the thermal energy, rh is the hydrodynamic radius, and η is the solvent viscosity).
