Abstract

The impact of various solvents on protein dynamics was investigated using Raman and neutron scattering spectra. Over the entire temperature range 100-350 K, the protein dynamics followed the dynamics of the solvents glycerol and trehalose. The behavior of the solvents was found sensitive to the protein's fast conformational fluctuations and low-frequency vibrations and their temperature variations. Glycerol acted as a biological cryopreservant, as shown by the results. The results also indicate that protein relaxation is stronger in solid trehalose than in liquid glycerol.
