Description
YEAtaq DNA Polymerase is a thermostable enzyme derived from the thermophilic bacterium Thermus aquaticus. It is able to withstand repeated heating to 95°C without significant loss of activity. The enzyme catalyzes 5’→3’ synthesis of DNA, has no detectable proofreading 3’→5’ exonuclease activity and possesses low 5’→3’ exonuclease activity. It also exhibits deoxynucleotidyl transferase activity, which normally results in the addition of extra adenines at the 3’-end of PCR products, required for the DNA ligation to TA vector.
Yeastern Biotech offers YEAtaq DNA Polymerase in two different packages: one with dNTPs mix and the other without.
The enzyme is in a recombinant form expressed in E. coli.
Features
• Thermostable : half life is more than 40 min at 95°C.
•10× Reaction Buffer is supplied with two components: KCl and (NH₄)₂SO₄, the latter allows for PCR at wide range of magnesium concentrations and decreases non-specific priming.
• Incorporates modified nucleotides (e.g., dUTP, dITP, biotin-, digoxigenin-, fluorescently-labeled nucleotides).
• The error rate of YEAtaq DNA Polymerase in PCR is 2×10-5 errors per nucleotide per cycle.
Applications
• Cloning
• Screening
• Primer extension
• Terminal dA tailing
• Routine PCR amplification of DNA fragments up to 3 Kb
• DNA labeling
• DNA sequencing
Unit Definition
One unit is defined as the amount of enzyme that will incorporate 10 nmol of dNTPs into 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 YEAtaq DNA polymerase in 50 μl reaction buffer for 18 hours at 37°C.
• The absence of endo-, exodeoxyribonucleases and ribonucleases is confirmed by appropriate tests. Functional test is performed by PCR.
