Accu DNA Polymerase

Accu DNA Polymerase is purified from an E. coli strain carrying a plasmid with a cloned gene encoding a Pyrococcus Sp. DNA polymerase. The enzyme catalyzes the incorporation of nucleotides into dsDNA in the 5'→3' direction in the presence of Mg2+ at 70 ~ 80°C. Accu DNA Polymerase exhibits 3'→5' exonuclease (proofreading) activity but has no detectable 5'→3' exonuclease activity. dUTP, dITP, and primers containing these nucleotides should not be used in PCR with Accu DNA polymerase because they inhibit DNA synthesis

Accu DNA Polymerase in two different packages is offered by Yeastern Biotech, one with dNTPs mix and the other without. A PCR premix format is also available with or without a green dye.

  • The error rate of Accu DNA polymerase in PCR is 2.6 × 10-6errors per nucleotide per cycle.
  • Eight times more accurate than Taq DNA polymerase.
  • Highly thermostable: remains 95% activity after 2 hours incubation at 95°C.
  • Generates blunt-end PCR products.
  • Incorporates modified nucleotides (e.g., biotin-, digoxigenin-, fluorescently-labeled nucleotides).
  • Cloning
  • Amplification
  • Mutation analysis
  • Accurate polymerization
  • Routine PCR amplification of DNA fragments up to 3 kb
  • RT-PCR
  • Blunt end amplification products
Unit Definition
One unit is defined as the amount of enzyme that will incorporate 10 nmol of dNTPs into the acid-insoluble material in 30 minutes at 72°C.

Quality Control
  • Nuclease activity is not detected after incubation of 1 μg λ /Hind III DNA with 5 units of Accu DNA polymerase in 50 μl reaction buffer for 18 hours at 37 °C.
  • The absence of endo-, exodeoxyribonucleases and ribonucleases are confirmed by appropriate tests. A functional test is performed by PCR.
