phi29 DNA Polymerase is a highly processive polymerase (up to more than 70 kb) featuring strong strand displacement activity, which allows for highly efficient isothermal DNA amplification. phi29 DNA Polymerase also possesses a 3'→5' exonuclease (proofreading) activity acting preferentially on single-stranded DNA or RNA. Therefore 3'-modified primers are highly recommended.


  • Highest processivity and strand displacement activity among known DNA polymerases – more than 70 kb long DNA stretches can be synthesized
  • Highly accurate DNA synthesis (see Reference 5)
  • Extremely high yields of amplified DNA even from minute amounts of template
  • Amplification products can be directly used in downstream applications (PCR, restriction digestion, SNP genotyping, etc.)
