Figure 5.

(A) Displacement of a CPεT receptor due to a flow rate of 10 μL/min (flow velocity: 0.0032 m/s), which starts at time t = 0 s. The drag force displaces the receptor until it reaches an equilibrium position where the restoring force of the actin skeleton is equal to the drag force. Note that absolute values of displacements are shown in this figure, in contrast to the data shown in Fig. 1D, Fig. 3, D–F, and Fig. 4C. (Solid line) Fit with the Kelvin-Voigt model ΔL(t) = σL₀/E(1−e^−λ/t) and gives σL₀/E = 2.22 ± 0.02 μm and λ = 0.49 ± 0.03 s⁻¹. (B) Displacement of a CPεT receptor due to a flow of 20 μL/min (flow speed: 0.0064 m/s) after latrunculin B treatment. The fit with the Kelvin-Voigt model gives σL₀/E = 7.38 ± 0.08 μm and λ = 1.2 ± 0.2 s⁻¹.
