MSDs for 1 (left), 2 (center), and 4.7 μm beads (right) in (a) 2.5 mg ml⁻¹, (b) 5 mg ml⁻¹, and (c) 10 mg ml⁻¹ fibrin gels. (d) Probability density functions of plateau MSD values for each gel concentration show the range of displacements measured for each bead size. MSD values for 4.7 μm beads in both 5 mg ml⁻¹ and 10 mg ml⁻¹ gels are indistinguishable from those of beads adherent to glass (not shown).
