Quasi-Elastic Behavior of Solutions of Viral Capsid and RNA at Very Low Shearing Stresses

By the application of shearing stresses on the order of 10-3dyne cm-2(10-2μ N cm-2), via the magnetic viscodensimeter, extremely high relative viscosities (>500) were observed when turnip yellow mosaic virus was degraded in alkali into its capsid and RNA. The solutions, however, possessed a water...

Description
Summary:By the application of shearing stresses on the order of 10-3dyne cm-2(10-2μ N cm-2), via the magnetic viscodensimeter, extremely high relative viscosities (>500) were observed when turnip yellow mosaic virus was degraded in alkali into its capsid and RNA. The solutions, however, possessed a watery consistency at this stage and exhibited a quasi-elastic character by rotor-recoil experiments. The development of this curious behavior was concentration and temperature dependent; it was not seen
