  • Title: Radiofrequency dielectric spectroscopy of ribosome suspensions.
    Author: Bonincontro A, Giansanti A, Pedone F, Risuleo G.
    Journal: Biochim Biophys Acta; 1991 Nov 14; 1115(1):49-53. PubMed ID: 1958704.
    Abstract:
    Dielectric measurements on different ribosome suspensions were carried out in the frequency range from 10 kHz to 1 GHz. In intact ribosomes two dispersions were detected: one around 100 kHz and the other one in the MHz region. In separated ribosomal subunits and in ribosomes resuspended in a buffer with no magnesium ions (relaxed ribosomes) only the MHz dispersion was observed. Electrical conductivities of the samples at 1 kHz were also measured. The temperature dependence of the two dispersions was investigated and a tentative attribution was proposed.
