Characteristics of the ribonucleoprotein of influenza virus A.
Ribonucleoproteins (RNP) of influenza viruses A/Singapore/1/57, A/Victoria/35/72 and those isolated in the course of passaging in persistent infection systems (influenza virus--diploid human lung cells) were subjected to desimentation analysis. In viruses of different antigenic structure the 3 RNP fragments had the same sedimentation coefficients (63, 53, and 42 S, respectively). The ratios of RNP fragment concentrations had an individual character and were in relation with the antigenic differences between the strains studied.
