产品信息

LongAmp® Taq DNA Polymerase is a unique blend of Taq and Deep Vent® DNA Polymerases. The 3´→5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase (1). LongAmp Taq DNA Polymerase offers two fold higher fidelity than Taq DNA Polymerase alone. A wide range of PCR products can be generated, up to 30 kb from lambda DNA or from human genomic DNA.

LongAmp® Taq DNA Polymerase |
Amplification of specific sequences from human genomic DNA using LongAmp Taq DNA Polymerase. Amplicon sizes are indicated below the gel. Marker M is the NEB 1 kb DNA Ladder (NEB #N3232).

产品来源
