Takara Ex Taq HS DNA Polymerase is the hot-start version of our high-performing Takara Ex Taq polymerase (a blend of Takara Taq and a proofreading exonuclease) offering high yield, excellent sensitivity, and fidelity that is 4.5-times higher than Taq polymerase. Antibody-mediated hot-start gives lower background, higher specificity, and allows room temperature reaction assembly. Takara Ex Taq HS DNA polymerase is supplied with 10X buffer (Mg2+) and dNTP mix.
Takara Ex Taq HS DNA polymerase includes a monoclonal antibody to Taq DNA Polymerase that binds to the polymerase and prevents nonspecific amplification due to mispriming and/or formation of primer dimers during reaction assembly. The antibody is then denatured during the initial PCR DNA-denaturation step, releasing the polymerase and allowing DNA synthesis to proceed. A premix Ex Taq is available for fast and sensitive real-time PCR.
Several other formats of Ex Taq are available:
- Individual components ofEx Taq enzyme mix, dNTP mixture, and 10X reaction buffer (with or without Mg2+)—for individual reaction setup and optimization.
- A 2X PCR master mix contains Ex Taq enzyme, reaction buffer (with Mg2+), and dNTP mixture—for a simple PCR setup and minimal pipetting steps.
- A loading dye-added 2X master mix (PerfectShot Ex Taq DNA Polymerase)—for convenient loading of PCR products in agarose gels.
Overview
- Antibody-mediated hot start: lower background, increased specificity, and room-temperature reaction assembly
- High-yield and high-sensitivity PCR
- Excellent on difficult templates
