Microtubules are important organizing structures of eukaroytic cells. They are electrically polar and have collective vibration modes from kHz to low THz region. In approximation of microtubule subunits (tubulin molecules) as rigid particles, we calculate electric field generated by optical branch of axial longitudinal vibration modes of microtubule. This oscillatory electric field, due to its complex spatial distribution, may play an important role in cellular temporal and spatial organization
