Hybrid DNA Polymerase

Catalog No. 2950

Quick Overview

Hybrid DNA Polymerase is a genetically engineered thermophilic DNA polymerase used in standard and high-fidelity PCR applications, GC-rich sequences, problematic secondary structures, and cloning of blunt-ended PCR products.

  • Ultrapure recombinant enzyme
  • Catalyzes the polymerization of nucleotides into duplex DNA in the 5'->3' direction in the presence of magnesium ions
  • Exhibits 3'->5' proofreading activity, resulting in an over 10-fold higher PCR fidelity than standard Taq DNA Polymerases
  • Generates blunt ends
  • Enhanced polymerase processivity allows shorter extension times


  • For use in standard and High-fidelity PCR
  • PCR of GC-rich sequences
  • Problematic secondary structures
  • Cloning of blunt-ended PCR products


Due to the genetic modification of Hybrid DNA Polymerase, the optimal reaction conditions, including annealing temperatures, differ from standard PCR protocols

PCR amplification using CHIMERx Hybrid DNA Polymerase

Lane M: molecular size marker - Perfect 1 kb DNA Ladder. Lanes 1.1 to 12 kb: PCR amplification reactions, using 1 unit of Hybrid DNA Polymerase and 100-500 ng of human genomic DNA as a template for 35 cycles in 50 μl reaction volume.

Quality Control

All preparations are assayed for contaminating 3'-exonuclease, and nonspecific single- and double-stranded DNase activities. Typical preparations are greater than 95% pure, as judged by SDS polyacrylamide gel electrophoresis.

Storage Conditions
