摘要: Abstract Linear simian virus 40 (SV40) DNA molecules of genome length and fragments smaller than when prepared with restriction endonucleases tested for transforming activity on primary cultures baby rat kidney cells. The linear (prepared R-EcoRI, R-BamHI, R-HpaII or R-HapII), a 74% fragment (EcoRI/HpaII HapII-A), 59% (BamHI/HapII-A) could all transform cells the same efficiency as circular SV40 DNA. All transformed lines contained SV40-specific T-antigen in 90 to 100% cells, which was taken evidence that transformation specific. entire early region Endo R-HpaI, introduced one break region, apparently inactivated capacity DNA, since no observed any three HpaI tested. Attempts were made rescue infectious from some by fusion permissive BSC-1 Infectious only recovered form I No be isolated other types
