NEURATH, A. ROBERT (The Wistar Institute, Philadelphia, Pa.), TADEUSZ J. WIKTOR, AND HILARY KoPROWSKI. Density gradient centrifugation studies on rabies virus. J. Bacteriol. 92:102-106. 1966.-Cesium chloride density gradient centrifugation of rabies virus revealed a heterogeneous population of infectious virus particles, the majority of which showed a density of 1.20 g/ml. From results obtained...
Rubella virus was centrifuged in sucrose density gradients. One of two densities could be ascribed to the virus, depending upon the suspending medium used. The virus was found at a density of 1.16 g/cm(3) after centrifugation for 18 hr in sucrose gradients prepared in distilled water. By contrast, when the sucrose gradients were prepared in tris(hydroxymethyl)aminomethane (Tris)buffer containin...
Preparative isopycnic density-gradient centrifugation is ordinarily done in high-speed swinging-bucket rotors such as the Spinco SW 39 and SW 25. In addition to requiring this special equipment, the technique is severely limited by the small number of samples and the low total-sample volume which may be used. In recent studies on methods for isolating small numbers of virus particles from tissu...
