Microtubule Contact Times after Zippering and Catastrophic Collisions in MBD-DsRed–Expressing Cells
| Contact Time (s)
|
||
|---|---|---|
| Microtubule Orientation Relative to the Cell Axis | Zippering | Catastrophic Collision |
| Transverse | 157 ± 89 (41) | 23 ± 14 (13)a |
| Longitudinal | 83 ± 25 (12)b | 20 ± 10 (20)c |
The data represent the average microtubule contact times ± sd (n = microtubules) after microtubule zippering or catastrophic collisions.
a
Comparison between the contact times for zippering and catastrophically colliding transverse microtubules: P-value ∼ 0.0001 (Mann-Whitney test).
b
Comparison between the contact times for zippering transverse and longitudinal microtubules: P-value ∼0.004 (Mann-Whitney test).
c
Comparison between the contact times for zippering and catastrophically colliding longitudinal microtubules: P-value ∼0.001 (Mann-Whitney test).
