Expand^™ High Fidelity PCR System

Each lot of Expand High Fidelity is function-tested in PCR using human genomic DNA and specific primers for collagen (1 kb amplified product) and the tPA gene (4.8 kb amplified product).

The Expand^™ High Fidelity PCR System is an enzyme blend delivering superior results with twofold higher yield and threefold greater fidelity compared to Taq DNA Polymerase. Choose Expand High Fidelity PCR System for the most sensitive PCR results for genomic targets up to 5 kb in length in:

• PCR
• RT-PCR

Use Expand High Fidelity PCR System, dNTPack with ready-to-use PCR nucleotide mix.
For maximum convenience, select the 2x concentrated ready-to-use High Fidelity Master.

Expand High Fidelity PCR System is a mixture of Taq DNA polymerase and a DNA polymerase with proofreading activity for high yield and fidelity. It is optimized for PCR of DNA fragments up to 5 kb.
Use 2.6 U for a standard 50 μl PCR.

Volume activity: 3.5 U/μl

• Use one enzyme for all applications.

Enjoy high yield, fidelity, and flexibility.

• Detect PCR products

previously undetectable and avoid false negatives.

• Achieve successful results

from small quantities of template DNA.

Expand High Fidelity PCR System is optimized to efficiently amplify DNA fragments up to 5 kb. PCR up to 9 kb is possible, with yield diminishing as DNA fragment length increases. The Expand High Fidelity PCR System is composed of an enzyme mix containing thermostable Taq DNA polymerase and a thermostable DNA polymerase with proofreading activity. The fidelity of DNA synthesis with Expand High Fidelity PCR System shows a threefold increase compared to Taq DNA polymerase. T/A cloning is recommended.

The 5′ → 3′ polymerase activity of Taq DNA Polymerase and the 3′ → 5′ exonuclease of the proofreading polymerase combine for improved performance and results; 3′ → 5′ exonuclease proofreading produces a threefold increase in DNA synthesis fidelity compared to Taq DNA polymerase.
