FIGURE 5.

Correlation between maximum tether length L_max at cycle n − 1 and regime transition length L_t at cycle n as defined on Fig. 4 a for ATP-depleted/inhibited RBCs compared to healthy RBCs. Each data point corresponds to a pair of successive extrusions. In a few cases, the transition between the two regimes is softer than usual so that the length L_t cannot be defined precisely. In these cases, an error bar is added, representing this imprecision. ATP-depleted/inhibited data corresponds to 30 extrusion pairs obtained on 11 different cells and healthy RBCs data corresponds to 17 extrusion pairs obtained on 11 different cells. ATP-depleted/inhibited cells data are fitted with a dotted line of slope 0.79 ± 0.05, healthy cells data are fitted with a solid line of slope 0.23 ± 0.07. These fits mean that L_t and L_max are significantly closer to each other but also more correlated for ATP-depleted/inhibited RBCs than for healthy RBCs.
