Fidelity at its finest.

Q5® High-Fidelity DNA Polymerase sets a new standard for both fidelity and robust performance. With the highest fidelity amplification available (~280 times higher than Taq), Q5 DNA Polymerase results in ultra-low error rates. Q5 DNA Polymerase is composed of a novel polymerase that is fused to the processivity-enhancing Sso7d DNA binding domain, improving speed, fidelity and reliability of performance. 

  • Highest fidelity amplification (~280X higher than Taq)
  • Ultra-low error rates
  • Superior performance for a broad range of amplicons (from high AT to high GC)
  • Hot start and master mix formats available
