Fusion of a Pyrococcus (Pfu) -like enzyme with a double-strand DNA binding domain → increased processivity.

Statistics about Phusion™ High-Fidelity DNA Polymerase

  • 10x processivity compared to Taq
  • 50x fidelity compared to Taq
  • Creates blunt end
  • Error rate is 4.4 X 10-7 in Phusion HF buffer and 9.5 X 10-7 in GC buffer
  • Non-displacing
