Quality Control for Current Lot


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

5 kb Lambda PCR:
25 cycles of PCR amplification of 5 ng Lambda DNA with 1.25 units of Taq DNA Polymerase in the presence of 200 µM dNTPs and 0.2 µM primers in Standard Taq Reaction Buffer results in the expected 5 kb product.

3´→ 5´ Exonuclease Activity:
Incubation of a 20 µl reaction in ThermoPol Reaction Buffer containing a minimum of 20 units of Taq DNA Polymerase with 10 nM fluorescent internally labeled oligonucleotide for 30 minutes at either 37°C or 75°C yields no detectable 3´→ 5´ degradation as determined by capillary electrophoresis.

Endonuclease Assay:
Incubation of a 50 µl reaction containing 20 units of Taq DNA Polymerasewith 1 µg of supercolied φX174 DNA for 4 hours at 75ºC resulted in < 10% conversion to the nicked form as determined by agarose gel electrophoresis.
