Stabilized branched actin filaments sliding along glass-anchored myosin 1b (corresponding to Fig. 2).
Branched filaments stabilized with phalloidin-Alexa547 in the absence of myosin (left) or sliding on Myo1b at high density (8000 μm-2). Scale bar 5 μm. Time in s. Wide field movies corresponding to time-lapse images shown in Fig. 1C.
