The ribonucleoprotein (RNP) internal components of influenza virus were separated into distinct size classes by sedimentation in glycerol gradients and examined by electron microscopy by using positive staining with uranyl acetate. The large RNP have a peak in length distribution at 90 to 110 nm, the medium, at 60 to 90 nm, and the small, at 30 to 50 nm. These lengths can be correlated with the estimated molecular weights of the ribonucleic acids contained in the various RNP size classes. The RNP structure appears to consist of a strand which is folded back on itself and coiled in a regular double-helical arrangement.
流感病毒的核糖核蛋白（RNP）内部成分通过在甘油梯度中沉降被分离成不同大小类别，并通过用醋酸铀进行正染色的电子显微镜检查。大的RNP长度分布峰值在90至110纳米，中等大小的在60至90纳米，小的在30至50纳米。这些长度可以与不同RNP大小类别中所含核糖核酸的估计分子量相关联。RNP结构似乎由一条自身折叠并以规则双螺旋排列盘绕的链组成。
