DB AptaTaq DNA Polymerase (DB-1277)

Use our DB AptaTaq DNA Polymerase in both PCR and RT-PCR to ensure excellent results in your applications (routine PCR amplification, high throughput PCR, TA cloning, DNA labelling)

DB AptaTaq DNA Polymerase

Thermostable Taq DNA Polymerase with aptamer-based hot-start

Highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus (half-life > 40 min at 95 °C)

Activities: Polymerase activity in direction 5’→3′ (synthesis of DNA), exonuclease activity in direction 5’→3′ (required for use in PCR with hydrolysis probes, e.g. TaqMan™ probes) and 5′ flap activity. No detectable exonuclease activity in the direction 3’→5′ (proofreading).

Aptamer-based hot-start for user-friendly preparation of PCR mix at ambient temperature.

Generation of PCR products with 3′ -dA overhangs for their use in TA cloning.

Recombinant protein expressed in E. coli

Supplied with complete PCR buffer (5X) including dNTPs and optimal concentration of MgCl2.
