title: Physical and chemical properties of an oncornavirus associated with a murine adrenal carcinoma cell line.
abstract: A type C oncornavirus has been isolated from a continuous cell line of murine adrenal carcinoma in culture. The particles have a buoyant density of 1.165 g/cm(3), exhibit typical type C morphology by electron microscopy, possess an RNA-dependent DNA polymerase, and have a high molecular weight RNA (6.1 x 10(6)) which can be denatured to a homogeneous lower molecular weight species (3.2 x 10(6)) when extracted from rapidly harvested "immature" virions. The virus is related antigenically to other mammalian oncornaviruses and exhibits a similar, although much more complex, sodium dodecyl sulfate gel electrophoretic profile of virion proteins when compared to the profiles of other type C RNA tumor viruses.
