  • FastTools Hi-Fi PCR Kit

    FastTools Hi-Fi PCR Kit

    Fast HiFidelity Polymerase is purified from the hyperthermophilic original strain Pyrococcus spp, with super 3'-5' exonuclease activity (Proofreading activity), and high fidelity- around 80 folds of Taq DNA Polymerase. This product uses innovative affinity ligands synthesis technology, in which ligands inhibit the activity of polymerase and exonuclease in a temperature dependent way. Ligand A inhibits DNA Polymerase activity at room temperature, which effectively reducing nonspecific amplification; ligand B inhibits the 3'–5' exonuclease activity and prevents the primer and template from degradation, therefore perform high specific Hot Start PCR reaction. PCR Enhancer in this product highly improves the extending speed. The PCR product is blunt-ended, could ligate with T vector after addition of “A”, or use blunt-end clone vector, as TOOLS ZBack Faster Ligation Kit (TGVTB04).

  • Tools Taq DNA Polymerase

    Tools Taq DNA Polymerase

    TOOLS Taq DNA Polymerase is a recombinant 94 kDa DNA polymerase expressed in an E.coli strain that carries the cloned Thermu aquaticus DNA Polymerase gene. It possesses both 5’-3’ polymerase and exonuclease activity, and has no detectable 3’-5’ exonuclease activity. The extension rate of TOOLS Taq DNA Polymerase is 1-2 kb/min in PCR. In addition, it has a 3’ adenylation activity. Thus, the PCR products can be used directly in TA-cloning procedures.

    Tools Taq DNA Polymerase w/o Mg2+

    TOOLS Taq DNA Polymerase is a recombinant 94 kDa DNA polymerase expressed in an E.coli strain that carries the cloned Thermu aquaticus DNA Polymerase gene. It possesses both 5’-3’ polymerase and exonuclease activity, and has no detectable 3’-5’ exonuclease activity. The extension rate of TOOLS Taq DNA Polymerase is 1-2 kb/min in PCR. In addition, it has a 3’ adenylation activity. Thus, the PCR products can be used directly in TA-cloning procedures.

  • Extra Long Taq DNA Polymerase

    Extra Long Taq DNA Polymerase

    ExtraLong Taq DNA Polymerase, a high fidelity of polymerases with 3’-5’ exonuclease activity designed for amplifying large fragment. A wide range of PCR products can be generated, up to 40 kb from lambda DNA and 30 kb from human genomic DNA. It is also a better choice for amplifying complex template, such as GC-rich template. ExtraLong Taq Polymerase is suitable as a direct replacement for ordinary Taq Polymerase in most applications. PCR products produced with ExtraLong Taq Polymerase can be used in either TA cloning or blunt cloning.

  • Super Hi-Fi Taq DNA Polymerase

    Super Hi-Fi Taq DNA Polymerase

    Super Hi-Fi Tag DNA Polymerase is a special blend of Taq polymerase and Pfu Polymerase. It possesses both 5’-3’ polymerase and exonuclease activity. The advantages of Super Hi-Fi Tag DNA Polymerase are high productivity and fidelity. Comparing to regular Taq polymerase, Super Hi-Fi Tag can efficiently amplify large DNA fragments (20Kb for simple templates and 10Kb for complex templates). Besides, it possesses higher extension rate and amplification efficiency than Pfu DNA Polymerase. Super Hi-Fi Tag DNA Polymerase generates PCR products with 3’-dA overhangs that can be directly used in TA-cloning. To obtain higher cloning efficiency, however, PCR products could be purified and added 3-d'A overhangs before TA cloning procedures.
