title: Efficient production of xenotropic murine leukemia virus unintegrated proviral DNA by cocultivation.
abstract: Cocultivation of virus-producing cells and homologous uninfected cells yielded greater than a 10-fold increase in linear and superhelical proviral DNAs as compared with previously published techniques.
