Like Taq, Tfi has 5' to 3' exonuclease and 5' to 3' polymerase activity. PCR performance is comparable to Taq DNA polymerase in yield, specificity, fidelity, and robustness. Tfi can be substituted for Taq DNA Polymerase in virtually any application and is ideal for genomic, cDNA, and plasmid targets up to 4kb in length. Tfican be considered for use as a component in a diagnostic application if qualified by the end user.

  • Eliminate licensing fees and restrictions associated with Taq-based enzymes
  • Save money-Tfiis less expensive than TaqDNA Polymerase
  • Achieve yield, specificity, and fidelity comparable to Taq DNA polymerase
  • No need to reoptimize - swap out Taq for Tfi

Tfi is also available in special pack sizes and for OEM customers who may require PCR kit manufacturing flexibility.
