Microtubules (MTs) are macromolecular structures consisting of tubulin heterodimers and present in almost
every eukaryotic cell. MTs fulfill all conditions for generation of electromagnetic field and are electrically polar due to the
electrical polarity of a tubulin heterodimer. The calculated static electric dipole moment of about 1000 Debye makes them
capable of being aligned parallel to the applied electromagnetic field direction. In the present study, the tubulin heterodimers
were extracted and purified from the rat brains. MTs were obtained by polymerization in vitro. Samples of microtubules
were adsorbed in the absence and in the presence of electromagnetic fields with radio frequency of 900 Hz. Our results
demonstrate the effect of electromagnetic field with 900 Hz frequency to change the structure of MTs. In this paper,
a related patent was used that will help to better understand the studied subject.
