A procedure has been described for the centrifugal fractionation of the cellular particulate components of CNS tissue infected with poliomyelitis virus. A study of the distribution of infectivity among these components revealed that approximately fou

Techniques for HCl hydrolysis and chromatography were modified to permit analysis of the bases in the RNA of representative strains of the three types of poliovirus. The base compositions of these strains were found to be essentially the same, but po

Sedimentation by one run in an angle centrifuge, without special precautions, in a series of sucrose concentrations, followed by assay of the solutions has been shown to yield reasonable sizes and, in some cases, densities of particles from 15 to 260

A procedure is described for the preparation of freshly harvested infectious tissue culture fluid for quantitative electron microscopy. The yield of characteristic physical particles per monkey kidney epithelial cell varied between 50,000 and 300,000
