A PCR GAME CHANGER
Description
VeriFi® Polymerase is a versatile and robust high fidelity DNA polymerase engineered for all PCR applications where greater sequence accuracy is required.
Improved DNA binding and increased processivity result in shorter extension times, higher yields and the ability to amplify longer and more difficult targets.
- High temperature cycling – up to 100°C denaturation to better separate GC-rich templates
- Increased PCR success rates with complex genomic templates (17.5kb and over)
- High yields under standard and fast PCR conditions (10-30s/kb)
- Efficient and specific amplification from challenging templates including GC and AT-rich sequences
- 100x higher fidelity than Taq DNA polymerase
- Generates blunt-end PCR products
Applications
- High fidelity PCR
- Long range PCR
- Site-directed mutagenesis
- Cloning
- Sequencing
VeriFi polymerase came to my rescue when I struggled with amplifying large vectors using regular xxx polymerase.
Its high fidelity and good yield made a noticeable difference. Further, the same polymerase can be used for amplifying fragments from genomic DNA, which is known to inhibit a lot of polymerases, therefore making it a true all-in-one solution. With over half a decade of experience, I confidently recommend it to anyone tackling large vectors.
Trust me, VeriFi will make your lab life a whole lot easier!

VeriFi® Polymerase is derived from Pfu DNA polymerase for its 3’-5’ exonuclease (proofreading) activity. The enzyme is engineered with proprietary mutations that significantly increase processivity, resulting in shorter extension times (10-30 s/kb), higher yields and the ability to amplify longer and more difficult targets, including eukaryotic genomic templates in excess of 17.5 kb.
The high accuracy and enhanced 3’-5’ exonuclease activity of VeriFi® Polymerase result in fidelity that is approximately 100 times higher than Taq DNA polymerase. The enzyme is ideally suited to applications where greater accuracy is required, such as cloning, site-directed mutagenesis and sequencing. PCR products generated with this range of products are blunt ended.
VeriFi® Polymerase enables high fidelity PCR of a wide range of targets and fragment sizes with minimal or no optimisation required. The enzyme is provided with an advanced buffer system including both dNTPs and Mg. For the most difficult templates, such as highly GC-rich sequences or those with complex secondary structures, users have the option of adding the VeriMax Enhancer to the reaction mix for improved PCR performance.
Figure 1. Versatility across a broad range of amplicon lengths
PCRBIO VeriFi™ Polymerase amplifies the range of fragment lengths indicated with high yield and specificity. The starting template amount is 4-30ng of mouse or human genomic DNA, diluted 1.5 to 3 fold. GC content ranges from 37-55%. L: PCRBIO Ladder II.
Figure 2. Increased success rates with complex templates
Amplification of a 17.5kb fragment of the HBB gene. The starting template amount is 150ng (A and C) and 30ng (B and D) of human genomic DNA, diluted 2 fold. A 2-step PCR protocol was used with amplification at 72°C (A and B) or 68°C (C and D). GC content is 37%. PCRBIO VeriFi™ Polymerase amplifies long fragments with yields comparable to Takara PrimeSTAR GXL DNA Polymerase. L: PCRBIO Ladder II.
Figure 3. Amplification of targets with high sensitivity and specificity compared to leading competitors
Amplification of a 1.0kb fragment of the GAPDH gene with different starting template amounts of mouse genomic DNA. A: 20ng, B: 3.2ng, C: 0.5ng, D: 0.08ng. GC content is 51%. L: PCRBIO Ladder IV. The reactions were set up following manufacturers’ recommendations. Cycling conditions were 95°C 2 min, then 30 cycles of 98°C 15 sec, 66°C 15 sec and 72°C 30 sec. PCRBIO VeriFi™ Polymerase displays greater sensitivity and specificity compared to leading competitors.
