title: The attachment and penetration of T7 DNA/phage in Syrian hamster embryonic cells.
abstract: Bacteriophage T7 DNA can penetrate Syrian hamster embryonic cells after a mandatory initial pretreatment with DEAE-dextran. In 3 h an extracellular complex between T7DNA and the cell monolayer is formed which is equivalent to 105 T7 genomes per cell. During the ensuing 24-48 h of cell growth, an average of 102-103 T7 genomes are transported to the nucleus in 90% of the cells of the culture.
