Human Cytomegalovirus: Purification of Enveloped Virions and Dense Bodies Talbot, P. and Almeida, June D.,, 36, 345-349 (1977), doi = https://doi.org/10.1099/0022-1317-36-2-345, publicationName = Microbiology Society, issn = 0022-1317, abstract= SUMMARY Enveloped virions and dense bodies of human cytomegalovirus have been purified by centrifugation, using combination negative viscosity: positive density gradients. Light-scattering bands of each component were obtained, and when these were examined by immune electron microscopy minimal cross contamination was observed., language=, type=
