Product Information
Applications:
- breakneck speed, >8-fold quicker than native Pfu and 4-fold faster than Taq
- Fast PCR ramping and thermocycling to shorten amplification timetables
- extremely processive, increases the yield and specificity of PCR products
- proofreading activity results in 80-fold lower PCR mutation frequency relative to native Taq
- amplicons are blunt PCR products
Source:
Incendio® fast DNA polymerase was originally sourced from a hyperthermophilic archaeon and improved through combinatorial protein engineering efforts such as directed evolution and rational design. The final engineered enzyme was synthesized as a codon-optimized minigene, was expressed heterologously in a chassis such as Escherichia coli or Vibrio natriegens with the assistance of chaperone proteins and was purified by proprietary chromatographic techniques. This product is manufactured in the USA using chemically-defined components and, therefore, does not contain manufacturing components such as serum or animal-derived raw materials. Incendio® is suitable for fast cycling applications and screening of long-range recombinant junctions to validate CRISPR-gene-edited loci.
Molecular Weight:
~90 kDa
Unit Definition:
One unit is defined as the amount of enzyme required to catalyze the incorporation of 10 nmol of dNTPs into acid insoluble material in 30 minutes at 72°C under standard DNA polymerase assay conditions.
Residual Nuclease Activity:
Incendio® is free from detectable RNase A, endonuclease (nicking) and non-specific DNase activities as determined by fluorometric assays using cleavable fluorescent-labeled substrates to be less than the limit of quantitation ≤ 0.3 pg/ml.
Heat Inactivation:
The polymerase is extremely thermostable, and unable to be heat-inactivated. Incendio® fast DNA polymerase half-life is ~12h at 95°C, ~3.5 h at 98°C.
Supplied With:
10x Incendio® Reaction Buffer
200 mM Tris pH 8.820 mM MgSO₄100 mM KCl80 mM (NH₄)₂SO₄0.5% Triton X-1000.1% IGEPAL CA-6301 mg/ml rHSA (recombinant human serum albumin)
Supplied In:
50 mM Tris-HCl (pH 8.0)0.1 mM EDTA1 mM TCEP0.001% Tween 200.001% IGEPAL CA-63050% (v/v) glycerol
Biological Activity:
Incendio® fast DNA polymerase is assayed for its specificity and efficiency in amplifying long fragment targets within the human and mouse genomes. A long-range PCR assay was developed for screening of mouse embryonic stem cell lysates at the CRISPR-edited safe harbor locus Rosa26. Screening across the recombinant junction of the 5’ Rosa26 homology arm is challenging due to high GC-content. Amplification with Incendio® DNA polymerase in a long-range PCR reaction yields a 2,257-bp 5’ Rosa26 amplicon.
Additionally, Incendio® fast DNA polymerase is tested for amplification of the full-length 17-kb human XIST cDNA using an abbreviated PCR extension step. The long XIST amplicon is separated by pulsed-field gel electrophoresis (PFGE) in 1% agarose gel containing a TBE buffer and Sanger sequenced to confirm PCR product identity.
Appearance:
A sterile, aqueous, clear and colorless solution.
Storage & Stability:
The product is shipped at ambient temperature. Upon receipt, store it immediately at -20°C.
Store Incendio® DNA polymerase, 10x PCR Buffer with Mg2+, 5x GC-enhancer, and dNTPs (if supplied) at -20°C. Use proper aseptic technique and work in a PCR workstation to avoid contamination of reagents.
These products may be shipped at room temperature or with blue ice and should be stored immediately upon arrival at -20°C. When stored under the recommended conditions and handled correctly, these products should be stable for at least 1 year from the date of receipt. Approximately 30 minutes before use, thaw the product and its components in an ice bucket and mix thoroughly by gently vortexing at a low speed. After thawing, these products should be kept on ice or a 4˚C cold block before use.
Avoid repeated freeze-thaw cycles by aliquoting to reduce the loss of enzymatic activity. Thawed aliquots are stable for 1-week if stored at 2-8˚ C.
