Exonuclease Activity (Radioactivity Release) | - A 50 µl reaction in ThermoPol® Reaction Buffer containing 1 µg of supercoiled PhiX174 DNA and a minimum of 20 units of Taq DNA Polymerase incubated for 4 hours at either 37°C or 75ºC results in |
Non-Specific DNase Activity (16 Hour) | - A 50 µl reaction in NEBuffer 2 containing 1 µg of T3 DNA in addition to a reaction containing Lambda-HindIII DNA and a minimum of 5 units of Taq DNA Polymerase incubated for A169PCR Amplification (5.0 kb Lambda DNA)16 hours at 37ºC results in a DNA pattern free of detectable nuclease degradation as determined by agarose gel electrophoresis |
PCR Amplification (5.0 kb Lambda DNA) | - A 50 µl reaction in ThermoPol® Reaction Buffer in the presence of 200 µM dNTPs and 0.2 µM primers containing 5 ng Lambda DNA with 1.25 units of Taq DNA Polymerase for 25 cycles of PCR amplification results in the expected 5.0 kb product. |
Phosphatase Activity (pNPP) | - A 200 µl reaction in 1M Diethanolamine, pH 9.8, 0.5 mM MgCl containing 2.5 mM p-Nitrophenyl Phosphate (pNPP) and a minimum of 100 units Taq DNA Polymerase incubated for 4 hours at 37°C yields <0.0001 unit of alkaline phosphatase activity as determined by spectrophotometric analysis. |
Protein Purity Assay (SDS-PAGE) | Taq DNA Polymerase is η 99% pure as determined by SDS-PAGE analysis using Coomassie Blue detection. |
qPCR DNA Contamination (E. coli Genomic) | A minimum of 5 units of Taq DNA Polymerase is screened for the presence of E. coli genomic DNA using SYBR® Green qPCR with primers specific for the E. coli 16S rRNA locus. Results are quantified using a standard curve generated from purified E. coli genomic DNA. The measured level of E. coli genomic DNA contamination is ζ 1 E. coli genome. |
