HelixAmp™ Xtender-Taq Polymerase is very suitable and ideal for long-ranged PCR up to ~40 kb from isolated viral DNAs or up to ~25 kb from genomic DNAs. This enzyme mixture is an optimized blend of HelixAmp™ Taq Polymerase and HelixAmp™ Power-Pfu Polymerase. Due to the proofreading activity of HelixAmp™ Power-Pfu Polymerase, HelixAmp™ Xtender-Taq Polymerase possesses the greater yield, processivity and fidelity than Taq DNA polymerase alone. The fidelity of HelixAmp™ Xtender-Taq Polymerase is higher approximately 4 times than that of HelixAmp™ Taq Polymerase. The high productivity of HelixAmp™ Xtender-Taq Polymerase is suited to the amplification of a low copy target DNA. The addition of TuneUp™ Solution in the reaction mixture is a simple way to optimize the long-range PCR.
