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. This diluent is recommended for making dilutions of Vent (exo-) Polymerase.
3. Additional ThermoPol Reaction Buffer Packs for this product are also available. Each buffer pack contains 4 vials of 10X buffer (1.5 ml each) and 1 vial of 100 mM MgSO₄.

1. Can Vent (exo-) DNA Polymerase be used in other buffers?
2. Are the DNA fragments produced by Vent (exo-) DNA Polymerase blunt-ended or do they have the single-base 3' overhang that Taq DNA Polymerase yields?
3. I can't get Vent (exo-) DNA Polymerase to work yet Taq DNA Polymerase works fine.
4. What should I take into consideration when designing a set of PCR primers?
5. How can I facilitate the amplification of templates with hairpin-loop structures or high GC-content?
