Deep Vent (exo-) DNA Polymerase has been genetically engineered to eliminate the 3´→ 5´ proofreading exonuclease activity associated with Deep Vent DNA Polymerase. Deep Vent (exo-) DNA Polymerase is even more stable than Vent® (exo-) DNA Polymerase with a half-life of 23 hours at 95°C and 8 hours at 100°C. Both Deep Vent (exo-) and Vent (exo-) DNA Polymerase are suitable for primer extensions and high temperature (72°C) DNA sequencing.

Deep Vent® (exo-) DNA Polymerase |


An E. coli strain that carries the Deep Vent (D141A / E143A) DNA Polymerase gene, a genetically engineered form of the native DNA polymerase from Pyrococcus species GB-D. The native organism was isolated from a submarine thermal vent at 2,010 meters (1) and is able to grow at temperatures as high as 104°C.

  • 注意事项
    1. BSA is not provided with this enzyme since its presence is not necessary for most primer extension reactions. However, it is available as NEB #B9001. Acetylated BSA should not be used for primer extension reactions.
    2. Diluent D is also available (#B8004). This diluent is recommended for making dilutions of Deep Vent (exo-) DNA Polymerase.
    3. Additional ThermoPol Reaction Buffer Packs are also available (#B9004). Each buffer pack contains 4 vials of 10X buffer (1.5 ml each) and 1 vial of 100 mM MgSO4.

FAQs & 问题解决指南

  • FAQs
    1. Are the DNA fragments produced by Deep Vent (exo-) DNA Polymerase blunt-ended or do they have the single-base 3′ overhang that Taq DNA Polymerase yields?
    2. Can Deep Vent (exo-) DNA Polymerase be used in other buffers?
    3. I can’t get Deep Vent (exo-) DNA Polymerase to work yet Taq DNA Polymerase works fine.
