Flexural Rigidity in the Presence of MAP2 Isoforms
| Isoform | EI | n | ||
|---|---|---|---|---|
| 10−24/Nm2 | ||||
| MAP2c | 15.1 ± 3.3 | 18 | ||
| MAP2d | 16.1 ± 2.7 | 8 | ||
| MAP2c3 | 14.5 ± 3.8 | 16 | ||
| Pure MT | 3.8 ± 0.9 | 16 | ||
| HT40 | 10.4 ± 3.1 | 28 | ||
| MAP mix | 16.0 ± 3.0 | 10 |
MAP2d has an additional repeat inserted between repeats 1 and 2; MAP2c3 has repeat 3 only. The values for pure tubulin microtubules, and microtubules in the presence of HT40 or mixture of brain MAPs, are also included for comparison. EI, flexural rigidity ± SD. n, number of experiments.
