I can tell you it is not an archael pol because they do not like dUTP
let alone ddUTP (they latch on and release it several thousand times
slower than other bases - LTI J.Biol.Chem paper 3-4 years ago.). Most
likely, if it is not being used for cycle sequencing, is a reasonably
thermophilic bacterial pol I like enzyme, probably a Klenow fragment i.e
5'-3' exo minus. So it could be Bacillus stearothermophilis or any other
bacterial thermophile growing at 55-65C. Even Taq pol will work happily
with ddUTP at 60C.
Who's selling it?
The problem with being on the cutting edge is that you occasionally get
sliced from time to time....
