Transformation of rodent cells by DNA extracted from transformation-defective adenovirus mutants

Complementation group II host range mutants of adenovirus type 5 which map in early region 1B (E1B, 4.5 to 11.0 map units) have been shown to be defective for the synthesis of the E1B 58,000-dalton (58K) antigen in infections of HeLa or KB cells (Lassam et al., Cell 18:781-791, 1979) and unable to transform cultured rodent cells (Graham et al., Virology 86:10-21, 1978). In this report we show that DNA extracted from group II mutants hr6 and …
