Whole plasmid PCR protocol using PFU Ultra DNA polymerase.


For a 50 μL whole plasmid PCR PCR reaction:

  • 35 μL H2O
  • 5 μL 10X PFU Ultra PCR buffer
  • 5 μL 2mM (each) dNTP mix
  • 1 μL 5nM plasmid template (0.1 nM final)
  • 1 μL 10μM sense primer (200nM final)
  • 1 μL 10μM antisense primer (200nM final)
  • 1 μL PFU Ultra DNA polyermerase
  • 1 μL PFU ligase


  1. In a PCR tube, mix the components on ice in the order they are listed above.
  2. Perform the following thermocycling program:
    1. 95 °C 1 min (initial melting)
    2. 95 °C 30 s (melting)
    3. TH = 55 °C 60 s (annealing, ligation)
    4. 72 °C 2 min for each 1 kb PCR product (elongation)
    5. Repeat steps 2-4 a total of 12-20 times (20 is standard).
    6. 72 °C 20 min (final elongation)
    7. 55 °C 60 min (final ligation)
    8. 12 °C hold
