Quality Control for Current Lot


Quality control values for a specific lot can be found on the datacard which accompanies each product.

Endonuclease Activity:
Incubation of a 50 μl reaction containing 20 units of Taq DNA Polymerase with ThermoPol Buffer with 1 μg of ΦX174 RF I DNA for 4 hours at 75ºC resulted in < 10% conversion to RFII as determined by agarose gel electrophoresis.

5 kb Lambda PCR:
25 cycles of PCR amplification of 5 ng Lambda DNA with 2.5 units of Taq DNA Polymerase in the presence of 200 µM dNTPS, 0.2 µM primers and 1X Standard Taq Reaction Buffer resulted in a yield of 200 ng specific product.

3´→ 5´ Exonuclease Activity:
Incubation of 20 units of Taq DNA Polymerase in 20 µl of a 10 nM solution of a fluorescent 5’-FAM labeled oligonucleotide for 30 minutes at 37°C and 75°C yields no detectable 3’-->5’ degradation as determined by high resolution denaturing PAGE.
