Thermal shape fluctuations of grafted microtubules were studied using high resolution particle tracking of attached fluorescent beads. First mode relaxation times were extracted from the mean square displacement in the transverse coordinate. For microtubules shorter than approximately 10 microm, the relaxation times were found to follow an L2 dependence instead of L4 as expected from the standard wormlike chain model. This length dependence is shown to result from a complex length dependence of… CONTINUE READING
