Fig. 2 |. Microtubule sliding speed is independent of polarity and motor concentration.

Fig. 2 |

Local measurements (2μm bins) from photobleaching of microtubule sliding speed and polarity, Pbleach, for different XCTK2 concentrations. The shaded regions indicate the 95% confidence intervals of a linear regression for each motor concentration. Inset: correlation between local polarity Pbleach of microtubule motion measured by bleaching and local physical polarity PSHG of microtubules measured by SHG. The black line is a linear regression and the shaded region indicates the corresponding 99% confidence interval.
