What are the differences between Taq and Pfu polymerases?

The main difference between Pfu and alternative enzymes is that Pfu has superior thermostability and proof-reading properties. Unlike Taq DNA polymerase, Pfu DNA polymerase also possesses 3′->5′ exonuclease proofreading activity, resulting in PCR fragments with fewer errors than Taq-generated PCR inserts.

What is Phusion polymerase?

Phusion Polymerase: robust and accurate high-fidelity PCR The enzyme, originally developed by Finnzymes, is a fusion of a proofreading polymerase and a processivity-enhancing domain, creating one of the most reliable and robust polymerases available.

Is Phusion High Fidelity DNA polymerase?

Thermo Scientific Phusion High-Fidelity DNA Polymerases set a gold standard for high performance PCR. Phusion DNA Polymerases offer robust performance with short protocol times, even in the presence of PCR inhibitors, and generate higher yields with lower enzyme amounts than other DNA polymerase.

Is Pfu a high fidelity polymerase?

High-Fidelity PCR. Pfu DNA Polymerase is a high-fidelity, thermostable enzyme of approximately 90kDa isolated from Pyrococcus furiosus. The enzyme replicates DNA at 75°C, catalyzing the polymerization of nucleotides in the 5´→3´ direction in the presence of magnesium.

Why is Pfu polymerase better than Taq polymerase?

Pfu Polymerases Unlike Taq DNA polymerase, Pfu DNA polymerase possesses 3′ to 5′ exonuclease proofreading activity, meaning that it works its way along the DNA from the 5′ end to the 3′ end and corrects nucleotide-misincorporation errors. The downside of Pfu is its speed which is slower that that of Taq.

What is in Phusion HF buffer?

5X Thermo Scientific Phusion HF Reaction Buffer is a buffer solution optimized for high-fidelity DNA amplification using Phusion High-Fidelity DNA polymerases. The buffer contains 7.5 mM MgCl2 which provides 1.5 mM MgCl2 in final reaction conditions.

Does Phusion polymerase create blunt ends?

Phusion® High-Fidelity DNA Polymerase produces blunt-end products. Phusion® is a registered trademark of Thermo Fisher Scientific.

What is the advantage of using a thermostable DNA polymerase?

Advantages of Taq DNA polymerase: Efficiency: It is highly efficient. As it is reached at its optimum temperature, the thermostable polymerase becomes fully functional and adds nucleotides to the growing DNA strand. High amplification capacity: It can insert 150 nucleotides per second during amplification.

What is Phusion buffer?

What is the protocol of Pfu DNA polymerase?

Pfu DNA Polymerase Protocol. Pfu DNA Polymerase is a thermostable enzyme that replicates DNA at 75°C. It catalyzes the polymerization of nucleotides into duplex DNA in the 5´→3´ direction in the presence of magnesium.

What is Invitrogen™ platinum PFX DNA polymerase?

The Invitrogen ™ Platinum Pfx DNA Polymerase is a proprietary enzyme preparation containing recombinant DNA polymerase from Thermococcus species KOD. The Platinum™ Pfx DNA Polymerase possesses proofreading 3¢ to 5¢ exonuclease activity and is a highly processive enzyme with fast chain extension capability.

What is PfuTurbo DNA polymerase?

Our PfuTurbo DNA Polymerase is a special formulation of cloned Pfu DNA polymerase and patented ArchaeMaxx Polymerase- Enhancing Factor that has been shown to increase PCR product yields up to 19 kb without affecting replication fidelity.

What is the difference between Taq and PfuTurbo DNA polymerase?

The PfuTurbo DNA Polymerase exhibits a lower error rate than other proofreading enzymes and a six-fold lower rate than Taq DNA polymerase. For Research Use Only.
