High-fidelity Pfu DNA Polymerase with 10x Buffer (Mg-free) and MgCl2

Pfu DNA Polymerase is a thermostable DNA polymerase that has 5´→ 3´ polymerase activity and 5´ flap endonuclease activity. The enzyme also exhibits 3´→5´ exonuclease (proofreading) activity.  Base misinsertions are rapidly removed by the polymerase, making it a good option for applications where high-fidelity error-free synthesis is required.  Edna Pfu products are recombinantly produced in E. coli and thus are highly pure and offer robust and reliable PCR activity.

What's In The Box:

The product includes a vial of the formulated recombinant enzyme along with 10X Pfu reaction buffer (Mg-free) which is detergent-free and designed to be compatible with existing assay systems. This product also includes a separate vial of 25 mM MgCl2 solution. 

Highlights:

• Isolated from a recombinant source

• The enzyme is free of any tags

• Supplied with 10X Reaction Buffer

• Robust and reliable reactions

• Tolerates a wide range of templates

• Incorporates dUTP, dITP and fluorescently-labeled nucleotides

• An ideal tool for amplifying DNA of length <5 kb
