Taq 2X Master Mix | NEB酶试剂 New England Biolabs
产品信息
Taq DNA Polymerase is a thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity (1,2,3) and a 5´ flap endonuclease activity (4,5).
Taq 2X Master Mix is an optimized ready-to-use solution containing Taq DNA Polymerase, dNTPs, MgCl2, KCI and stabilizers. It is ideally suited to routine PCR applications from templates including pure DNA solutions, bacterial colonies, and cDNA products. It can amplify up to 4 kb from complex genomic DNA or up to 5 kb from lambda DNA.

- 注意事项
- Taq 2X Master Mix should be used at a 1X concentration with DNA template and primers in a total reaction volume of 25 or 50 μl.
- Taq 2X Master Mix is stable for fifteen freeze-thaw cycles when stored at -20°C
- Taq 2X Master Mix is also stable for three months at 4°C, so for frequent use, an aliquot may be kept at 4°C.
