Autor: Gianfranco Risuleo, Adalberto Bonincontro

Publikováno v: Advances in Molecular Imaging. :1-15

Electrorotation (ER) is a technique allowing the characterization of the surface properties of a variety of supra-molecular aggregates and living cultured cells as well as cellular organelles and biological materials in general. In particular, this t

Alterations of the Plasma Membrane Caused by Murine Polyomavirus Proliferation: An Electrorotation Study

Autor: Cecilia Aiello, Valerio Berardi, Adalberto Bonincontro, Gianfranco Risuleo

Publikováno v: Journal of Membrane Biology. 229:19-25

In this report we investigate the alterations of the dielectric properties of the plasma membrane caused by the infection of cultured fibroblasts with murine polyomavirus. The approach consists in a well-established dielectric spectroscopy technique,
