Fig. 2. (A) Distributions of the microtubule sliding patterns (Pattern) and the doublet present at the dynein-exposed edge of the active area (Doublet Number) following the induction of microtubule sliding in low Ca²⁺ buffer. For sliding pattern data, A54-e18: 3 trials, n=110. 137c: 3 trials, n=145. For doublet number data: A54-e18: 3 trials, n=63. 137c: 3 trials, n=33. (B) Distributions of the microtubule sliding patterns (Pattern) and the doublet present at the dynein-exposed edge of the active area (Doublet Number) following the induction of microtubule sliding in high Ca²⁺ buffer. For sliding pattern data: A54-e18: 3 trials, n=171; 137c: 3 trials, n=90. For doublet number data: A54-e18: 3 trials, n=81; 137c: 3 trials, n=27.
