On the structural features of influenza A nucleoprotein particles from small-angle X-ray scattering data

The structure of ribonucleic particles of influenza A virus of the A/California/07/09pdm strain is investigated by transmission electron microscopy and small-angle X-ray scattering. The small-angle X-ray scattering data obtained at room temperature correspond to previously reported data of ribonucleic particles of this virus. At higher temperatures, noticeable changes in the morphology of ribonucleic complexes are observed.
