We have reported that polymer-actin complexes are obtained by mixing F-actin with synthetic polymers carrying positive charges. We found that the polymer-actin complex shows various morphology depending on polycation and salt concentration. In this study, we report that the three dimensional structure analysis of polymer-actin complexes by using transmission electron microtomography (TEMT). We found that the polymer-actin complex is flattened bundle in the low salt concentration, while that is cylindrical bundle in high salt concentration. It means that three dimensional structure of polymer-actin complex is determined by the magnitude of electrostatic repulsion force in F-actins.
