Taq Highlights
Taq DNA polymerase is a thermostable DNA polymerase (DNAP) that catalyzes 5′ → 3′ DNA synthesis. Taq DNA polymerase has 5′ → 3′ exonuclease activity making it suitable for probe digestion and lacks 3′ → 5′ exonuclease activity.
- Strong terminal transferase activity enables A-tailing to support AT ligation chemistries and cloning
- Reduce material costs with a drop-in solution that delivers equivalent performance at a differentiated price-point
- Custom formats, including high concentration, support lyophilization applications
- Highly stringent enzyme manufacturing ensures quality performance across lots
Applications
- 3′ dA-tailing (A-tailing)
- NGS library preparation
- PCR amplification (fragments ≤ 5kb)
- Cloning
