Pfx DNA Polymerase is a highly thermostable recombinant DNA polymerase
derived from Pyrococcus sp. strain KOD i.e. no blend.

Pyrococcus sp. KOD has now been re-assigned taxonomically as a
Thermococcus sp. KOD. Polymerase aa sequence is very very similar to
9N7, as was sold by NEB.

Thermococcus gorgonarius - typing in Tgo polymerase in Google gives
loads of info!

Just to add to the info. Turbo Pfu is Pfu plus accessory polymerase
enhancing factors i.e. two other proteins. US Patent just granted to

It might look like I'm doing nothing, but at the cellular level I'm really
quite busy.
