| Research Abstract |
Structure and dynamics of a protein in aqueous solution were investigated by small-angle neutron scattering (SANS) and neutron spin echo (NSE) technique. Staphylococcal nuclease (SNase) was used as a model protein, and the SANS experiments were performed with BL15 “Taikan” diffractometer at MLF, J-PARC; and the NSE measurements were done by using IN15 spectrometer at ILL in France. The obtained scattering data were quantitatively analyzed, which led to the evaluation of the structure and dynamics of SNase in aqua.
