Figure 5.
Real-time movie frames showing an RBC undergoing tank treading (frequency 1 s−1). Each frame is separated from the previous one by 1 s. (Arrows) Two Heinz bodies within the RBC, one very close to the membrane (Bead 2) and one away from it (Bead 1, located deeper within the cytoplasm). At each rotation cycle, the outer bead (Bead 2) is at the same place as during the start of the cycle whereas the inner bead (Bead 1) develops a distinct lag. Cartoon depictions are given alongside the movie frames.
