Isopycnic centrifugation of infantile gastroenteritis virus (orbivirus group) in a CsCl gradient produced up to four bands at densities 1.38, 1.36, 1.30 and 1.28 g/ml. The particles in the bands had sedimentation coefficients of 380-400S, 520-530S, 270-280S and 320-330S, respectively. Whereas the 1.38 and 1.36 g/ml particles contained RNA, the 1.30 and 1.28 g/ml particles lacked RNA. Upon heating at 37 degrees, the 1.36 g/ml particles broke down into particles of higher and lower density.
在氯化铯梯度中对婴儿肠胃炎病毒（环状病毒属）进行等密度离心，可产生多达四条带，密度分别为1.38、1.36、1.30和1.28克/毫升。这些带中的颗粒沉降系数分别为380 - 400S、520 - 530S、270 - 280S和320 - 330S。密度为1.38和1.36克/毫升的颗粒含有RNA，而密度为1.30和1.28克/毫升的颗粒不含RNA。在37摄氏度加热时，密度为1.36克/毫升的颗粒分解为密度更高和更低的颗粒。
