N-terminal truncated Taq DNA Polymerase with reversible hot start system and no 5'-3' exonuclease activity for optimal detection of mismatches; lyo ready formulation for preparation of dried amplification mixes.
AptaTaq DNA exo Polymerase is a blend of N-terminal truncated Taq DNA Polymerase and a specific oligonucleotide (aptamer) with hot start features, optimized for excellent discrimination against misextension. This concentrated formulation contains no glycerol and is suitable for the preparation of dried-down amplification mix preparations.
  • Optimize your SNP analysis.
    Discriminate between paired and unpaired primer ends using an enzyme optimized for allele-specific PCR.
  • Obtain reliable results fast.
    Benefit from the general features of the AptaTaq DNA Polymerase System with the discriminating capabilities of a 5'-3' exonuclease activity-lacking Taq DNA Polymerase.
  • Prepare stable amplification mixes in dry format.
    Use this formulation for producing dried-down amplification mixes stable at room temperature.
Use AptaTaq exo DNA Polymerase for:
  • SNP analysis and genotyping
  • Allele-specific PCR
  • Multiplexing
  • Arbitrarily primed PCR
  • Formulation of dried-down amplification reagents

When time to result matters, this novel hot start technology is ideal as it does not require any activation time.
AptaTaq exoDNA Polymerase is active at temperatures above +60 to +65°C and inactive below +55°C. This hot start feature eliminates the risk of nonspecific primer extension. Taq DNA Polymerase itself is a highly processive 5'-3' DNA Polymerase lacking 5'-3' and 3'-5' exonuclease activity. Taq DNA Polymerase is stable during prolonged incubations at elevated temperatures (+95°C). The enzyme exhibits highest activity at a pH of approximately 9 (adjusted at +20°C) and temperatures approximately +75°C. Taq DNA Polymerase accepts dNTP analogs as substrates.
