    Abstract:
    Dissociation of influenza virus RNP under the effect of salt was studied. Separation of RNA and protein components of influenza virus RNP was shown to occur in a linear 15-30% sucrose concentration gradient containing 1.1 M NaCl. Upon RNP dissociation, protein-protein interactions between individual molecules of the structural protein were retained. The sedimentation coefficient of the protein component was 52S. The possibility of reassociation of the RNA-protein complex was studied. More complete reassociation was observed to occur in the presence of 0.1 M NaCl. The resulting RNA-protein complex morphologically is similar to the native RNP of influenza virus.
