RANGER DNA Polymerase is highly suitable for all PCR applications of long templates, including sequencing, mapping of chromosomal translocation breakpoints and other structural variations, as well as TA cloning.

Features & Benefits

  • Fast antibody-based hot-start polymerase - for highest specificity and speed
  • Superior performance - unique buffer system, including ultra-pure dNTPs and MgCl2
  • Higher-fidelity than Taq - Suitable for all long range applications


  • Validated for human genomic DNA up to 25 kb
  • Suitable for TA cloning


RANGER DNA Polymerase is a hot-start enzyme, possessing 5´→3´ DNA polymerase and 3´→5´ proofreading exonuclease activities, thus offering both higher-fidelity and enhanced specificity. The polymerase is supplied with an optimized buffer system, specially formulated and validated for the unique properties of RANGER. The buffer contains dNTPs, MgCl2 and enhancers at concentrations formulated to deliver the best results.

RANGER DNA Polymerase is an easy-to-use high-performance enzyme designed to amplify templates up to 25 kb with extreme sensitivity (Fig. 1). RANGER DNA Polymerase has the added convenience of room temperature reaction assembly due to its antibody-based hot-start property. This reduces unwanted non-specific amplification such as primer-dimer formation.
