A murine oncornavirus marker in adenovirus 7-transformed mouse cells.
The presence of oncornavirus particles in BALB/c mouse cells transformed by adenovirus 7 was investigated. The particles detected had a buoyant density of 1.16 g/cm3; both p30 and adenovirus T-specific immunofluorescence was demonstrated in the cell cytoplasm. No C-particles were shown by the electron microscope.
