Description

Thermo Scientific Phusion U DNA polymerase is a novel engineered high fidelity enzyme developed using fusion technology. Due to a proprietary mutation in the so called dUTP binding pocket of Phusion, Phusion U overcomes an important limitation of proofreading enzymes - it is able to incorporate dUTP and read through uracil present in DNA templates.
In addition to uracil usage possibility, Phusion U features all the superior properties of other Phusion DNA Polymerases - great accuracy, speed, ability to amplify long amplicons up to 20 kb and a high specificity with Affibody based hot start . These features make Phusion U Hot Start DNA Polymerase an excellent choice for such important applications as amplification of bisulphite-converted or damaged DNA as well as use of carryover contamination control.
Phusion U Hot Start DNA Polymerase is also available in the Master Mix and Green formats. Phusion U Hot Start PCR Master Mix is convenient 2X mix designed to minimize the number of pipetting steps. Only template and primers need to be added by the user. Phusion U Green format is a combination of Phusion U Hot Start DNA Polymerase and 5X Phusion Green Buffers. The buffers include a density reagent and two tracking dyes for direct loading of PCR products on a gel. The colored buffer does not interfere with Phusion U performance and is compatible with downstream applications such as DNA sequencing, ligation and restriction digestion.

Highlights

• Accuracy - extremely high fidelity DNA polymerase (25x Taq)
• Uracil-tolerance - engineered to incorporate dUTP and amplify uracil containing templates
• Specificity - hot start for reduced nonspecific amplification and primer degradation.
• Speed - short extension times (15-30 s/kb)
• Direct loading of PCR products on gels

Applications

• Amplification of bisulphite-converted DNA
• Amplification of damaged or aged DNA
• Carry-over contamination control
• Uracil-excision based (USER) cloning methods
