DB AptaTaq Polymerase

DB AptaTaq DNA Polymerase (DB-1277)

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.
