Taq DNA Polymerase is the industry standard for routine PCR. Taq with Standard Taq Buffer (NEB #M0273) is available in economical extra-large pack sizes. NEB provides high quality recombinant Taq at an exceptional value. Taq is available with different formats to accommodate a variety of PCR applications. For example, Taq with standard Taq Buffer is designed to support existing PCR platforms, while Hot Start Taq formulations (NEB #M0495) are also available for flexibility during reaction setup and increased specificity.
Taq DNA Polymerase is available in several convenient formats. The Taq PCR kit (NEB #E5000) includes all the reagents for 200 reactions. Taq 2X (NEB #M0270) or 5X (NEB #M0285) Master Mixes are ideal for high-throughput applications. Quick-Load® Taq 2X Master Mix (NEB #M0271) includes dye for direct gel loading.For exceptional performance across a wide range of templates, try OneTaq or OneTaq Hot Start.

Template/product specificity: Is RNA or DNA involved? Is the 3´ terminus at a gap, nick or at the end of the template?
Removal of existing nucleotides: Will the nucleotide(s) be removed from the existing polynucleotide chain as part of the protocol? If so, will they be removed from the 5´ or the 3´ end?
Thermal stability: Does the polymerase need to survive incubation at high temperature or is heat inactivation desirable?
Fidelity: Will subsequent sequence analysis or expression depend on the fidelity of the synthesized products?
