title: Comparative studies on functions of human adenovirus type 12 and its low oncogenic mutant virions.
abstract: Physical and biological properties of highly oncogenic human adenovirus type 12 were compared with a low oncogenic mutant (cyt mutant). Parental and cyt mutant virions had very similar density and DNA size. However, the parental strain virion preparations contained a much higher proportion of defective virions (capable of cell killing, but not able to induce T- or V-antigen) than cyt mutant stock. It was also found that cyt mutant had a reduced virus yield in several human cell lines compared with the parental strain.
