DESCRIPTION
Pfu DNA Polymerase is a highly purified recombinant highly thermostable DNA polymerase that has been isolated from E. coli carrying a vector encoding the Pyrococcus furiosus DNA polymerase gene. The enzyme is twenty-five times more accurate than Taq DNA Polymerase and it produces blunt-end amplicons.
High Fidelity DNA Polymerase is a blend of DNA polymerases specially designed for the highly accurate and efficient amplification of fragments up to 30 kb including GC-rich or other difficult templates.

B. DNA Polymerase
For amplification of longer fragments of an animal genomic DNA, the amount of enzyme should be increased to 2 or 2.5 U.
C. 5x Band Doctor
The use of Band doctor is not necessary in general, but helps in the amplification of DNA with high GC content and complex structures. The included 5x Band doctor can be added to the reaction mixture at the final concentration of 0.5x – 2x.

E. Extension Time
The extension time should be 2 min/kb for pfu Polymerase. For High Fidelity Polymerase the extension time should be 30 sec/kb for short fragments and 1 min/kb for fragments longer than 5 kb.
For the amplification of fragments longer than 5 kb, the temperature ought to be assigned at 68°C.
STORAGE
Store at -20°C for 24 months.
