Pfu DNA Polymerase
EBT-1011
500 unit (5 unit/㎕)

DESCRIPTION
Recombinant Pfu DNA Polymerase is purified from an E.coli strain carrying a plasmid with the cloned gene encoding Pyrococcus furiosus DNA polymerase. The enzyme catalyzes the incorporation of nucleotides into duplex DNA in the 5´->3´ direction in the presence of Mg²⁺ at 70-80°C. Pfu DNA Polymerase exhibits 3´-> 5´ exonuclease (proof-reading) activity, but has no detectable 5´->3´ exonuclease activity. The amplified products by Pfu DNA Polymerase can be used for a gene cloning with decreased error rate, and for a site-specific mutagenesis. Pfu DNA Polymerase, like any other polymerases showing proof-reading activity, generates PCR products with blunt end.

Pfu DNA Polymerase is recommended for an amplification of DNA fragment smaller than 7 kbp. Pfu DNA Polymerase is provided with 10x optimized reaction buffer.
