By using appropriate amounts of four bacteriophage phi 29 DNA replication proteins--terminal protein, DNA polymerase, protein p6 (double-stranded DNA-binding protein), and protein p5 (single-stranded DNA-binding protein)--it has been possible to amplify limited amounts of the 19,285-bp-long phi 29 DNA molecule by three orders of magnitude after 1 hr of incubation at 30 degrees C. Moreover, the quality of the amplified material was demonstrated by transfection experiments, in which infectivity of the synthetic (amplified) phi 29 DNA, measured as the ability to produce phage particles, was identical to that of the natural phi 29 DNA obtained from virions. The results presented in this paper establish some of the requisites for the development of isothermal DNA amplification strategies based on the bacteriophage phi 29 DNA replication machinery that are suitable for the amplification of very large (> 70 kb) segments of DNA.
