A loading dye-added 2X master mix (PerfectShot Ex Taq DNA Polymerase) is available for convenient loading of PCR products in agarose gels.
Ex Taq is also available in the following formats:
- Individual components—including Ex Taq polymerase mix, dNTP mixture, and 10X reaction buffer (with or without Mg2+) for individual reaction setup and optimization.
- An antibody-mediated hot-start version—for preventing non-specific amplification from mispriming during reaction setup.
Overview
- High-yield, high-sensitivity PCR
- Premixed PCR master mix for convenient amplification requiring minimal assembly
- Generation of PCR products having >80% cloning efficiency in T-vectors
More Information
Applications
- Ideal for high-fidelity, high-yield endpoint PCR
PCR products
PCR products generated with Ex Taq DNA Polymerase contain a mixture of 3'-A overhangs and blunt ends, resulting in >80% cloning efficiency in T-vectors.
