| The electric properties of a single microtubule filament were studied by observing the orientation process of microtubules in an alternating electric field under dark-field microscopy. The movie shows the movement of a single microtubule filament during application (indicated by ←→) of an alternating electric field of 105V/m at a frequency of 1 MHz. |
