Abstract

A method for intracellular amplification of DNA is disclosed. The method includes providing a mammalian cell with a first nucleic acid sequence encoding functional adenoviral E2A and E2B gene products and with a second nucleic acid sequence encoding a linear DNA fragment to be amplified. The second nucleic acid sequence further has at least one functional adenoviral Inverted Terminal Repeat on a terminus and, in one embodiment where there is only a single ITR, a hairpin-like structure on the other terminus. This allows the linear DNA fragment to be acted upon by the adenoviral E2A and E2B gene products, thus intracellularly amplifying the linear DNA fragment, which can be extracted.
