Q5 High-Fidelity DNA Polymerase sets a new standard for both fidelity and robust performance.



  • Includes Q5 High-Fidelity master mix and quick-load DNA ladder in a convenient kit format

  • 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


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. This kit contains a sufficient supply of master mix and nuclease-free water to perform 50 polymerase chain reactions or 200 reactions. For added convenience, gel loading dye, and a Quick-Load DNA ladder are also included in this kit.
