Improved version of the most accurate hot start DNA polymerase available

Proofreading DNA polymerase with superior features

Finnzymes’ Phusion® Hot Start High-Fidelity DNA Polymerase is the most accurate hot start DNA polymerase in the market. It has now been upgraded to allow the use of even wider range of primers, including those with low melting temperatures. The new Phusion® Hot Start II DNA Polymerase is ideal for PCR applications from routine PCR to highly demanding applications such as cloning and high-throughput PCR. Like all Phusion DNA Polymerases, it incorporates a unique dsDNA-binding domain making this Pyrococcus-like proofreading DNA polymerase extremely robust, rapid, and accurate.

Advantages

• No annealing temperature limitations
• Allows reaction setup at room temperature
• Zero-time reactivation due to unique hot start technology
• Fast PCR enzyme with extreme fidelity (over 6 times more accurate than Pfu)
• High product yields with low enzyme amounts gives excellent cost/reaction ratio
• Robust enzyme with high tolerance against PCR inhibitors requires minimal optimization

Extreme specificity with improved performance

At room temperature Phusion Hot Start II DNA Polymerase is inactivated by a reversibly binding Affibody® molecule, which makes the enzyme extremely specific. Hot start modification also prevents primer degradation during reaction setup. The unique hot start technology allows zero-time reactivation of the enzyme at standard cycling temperatures. The new Affibody molecule utilized in the Phusion Hot Start II DNA Polymerase sets no temperature limitations in the annealing step of the PCR protocol. This improvement allows the use of a very wide range of primers, including those with low melting temperatures.

Phusion Hot Start II DNA Polymerase provides extreme specificity and abundant yields. Five proofreading DNA polymerases from major suppliers were used to amplify 1.7-2.3 kb amplicons from human genomic DNA. All amplifications were performed in accordance with manufacturers’ instructions. Phusion Hot Start II DNA Polymerase provided high yields of specific products whereas all other enzymes delivered lower or no yields, some of them also amplifying non-specific products.
