Applications

  • Fast PCR with a standard PCR thermocycler.
  • Fast PCR of templates with up to 80% GC content, amplicons longer than 30 kb, and multiplex PCR.

Fast PCR can be achieved using fast PCR instrumentation or by using enzyme/reagent combinations that improve PCR efficiency. With a standard thermocycler, the TAQXpedite™ PCR system achieves fast PCR results with total reaction time as little as 16 minutes for a 500-bp amplicon (Table 1, Fig. 1). The TAQXpedite™ kit can be used with a either a specialized fast PCR thermocycler or a standard thermocycler.

The TAQXpedite PCR System (FAST End-Point) contains a unique blend of thermostable DNA polymerases that can be used for fast PCR, a carefully optimized 2X Universal MasterMix and a Difficult/Long MasterMix with all four dNTPs, and an optimized MgCl2 concentration. The MasterMix also contains EPICENTRE's patented PCR Enhancer with betaine,* which substantially improves the yield, efficiency, and specificity of amplification of many target sequences, especially those containing a high GC content or secondary structure.1-5 The TAQXpedite PCR System's Universal Master-Mix is designed for routine and/or high-throughput fast PCR applications (Fig. 1), while the Difficult/Long MasterMix is designed for use with troublesome, non-routine, or long applications (Fig. 2). All reaction components are included in the kit except for template and primers.

Benefits

  • Increased sample throughput.
  • High fidelity due to proofreading capabilities.
  • Two convenient MasterMixes for universal and difficult/long amplifications.
