Extracts from several simian virus 40 (SV40)-transformed nonproducer cells were prepared by the hot-phenol procedure normally used to extract cellular RNA. These extracts contained SV40 infectious units. Part of the infectious units were identified as SV40 form I DNA molecules. The results of reconstruction experiments suggest that SV40 form I DNA is extractable by the hot-phenol procedure because of its fast renaturation rate. The significance of the presence of free viral DNA in nonproducer transformed cells is discussed.
通过通常用于提取细胞RNA的热酚法制备了几种猿猴病毒40(SV40)转化的非生产性细胞的提取物。这些提取物含有SV40感染单位。部分感染单位被鉴定为SV40 I型DNA分子。重建实验结果表明,SV40 I型DNA因其快速复性率可通过热酚法提取。本文讨论了非生产性转化细胞中游离病毒DNA存在的意义。
