Product Information
UltraHiPF® DNA Polymerase is a heat-resistant ultra-fidelity DNA polymerase with 5′-3′ polymerase activity and 3′-5′ exonuclease activity. The polymerase can amplify uracil- and hypoxanthine- containing templates, GC- or AT- rich templates, genomes as low as one copy, and DNA fragments of more than 12 kb from different species. UltraHiPF® DNA Polymerase can specifically amplify 2 kb fragments at 1sec denaturation, annealing, and elongation, and can expand complex templates at 15-30 sec/kb. With Sanger sequencing, the mutation rate of this enzyme was 55 times lower than that of Taq DNA polymerase. The PCR product obtained by using the product has the Blunt-end.
Advantages
- 55X higher fidelity than Taq
- Robust Reactions – maximal success with minimal optimization
- Most templates can be expanded up to 0.5 sec/kb
- Superior performance for a broad range of amplicons
Performance Data
Uracil and hypoxanthine amplification function
Figure 1. Using Lambda DNA as template and adding 0.2mM dUTP, UltraHiPF DNA Polymerase was used to amplify the 2 kb target fragment. Then uracil-DNA glycosylase (UDG) was treated at 37℃ for 1 h followed by agarose gel electrophoresis.
High expansion rate
Figure 2. Using UltraHiPF DNA Polymerase to amplify the 2 kb fragments of Lambda DNA, Adenovirus DNA and K562 genome. The denaturation, annealing and elongation times of the program were set to 1 second.
High fidelity
Figure 3. Using UltraHiPF DNA Polymerase, V Competitor, and N Competitor DNA Polymerasee to amplifythe same 2.5Kb fragment LacIOZa template. Cloning products were used for Sanger sequencing.
Wide GC template amplification performance

Different length amplification performance
Figure 6. Using Lambda DNA, Adenovirus DNA and K562 genomes as templates, UltraHiPF DNA Polymerasee, V Competitor and N competitor DNA Polymerase were used to amplify the target fragments of 2kb, 5kb, 8kb and 12kb.
