title: Large-scale production, concentration and purification of Rous Sarcoma Virus in tissue culture.
abstract: A method is described for long-term standard production of purified virus from cultures of PR-RSV-C-transformed chicken cells. The mean yields were 4.91 mg of purified virus per liter of culture medium. Cells were grown in long-term cultures for 26 weeks. A combination of polyethylene glycol 6 000 precipitation and zonal centrifugation has been found satisfactory for virus concentration and purification.
