The invention relates to a DNA and RNA polymerases which have increased fidelity (or reduced misincorporation rate). In particular the invention , relates to a method of making such polymerases by increasing or enhancing 3'- 5' exonuclease activity of a polymerase for example, substituting the 3'-5' , exonuclease domain of one polymerase with a 3'-5'exonuclease domain with the desired activity from another polymerase. The invention also relates to DNA molecules containing the genes encoding the polymerases of the invention to , host cells containing such DNA molecules and to methods to make the polymerases using such host cells. The polymerases of the invention are particularly suited …

Why it's free to use
- Filed July 11, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 11, 2021.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
