A polymerase protein originating from a eukaryotic cell and involved in the RNA silencing pathway is for the first time provided in a purified soluble form that possesses a detectable RNA polymerization activity. This polymerase is useful in methods and kits for in vitro RNA synthesis. A polymerase of the invention copies ssRNA templates to produce two types of reaction products: short and long RNA copies. It can also copy ssDNA templates. The polymerization does not require a primer for the initiation of RNA synthesis although RNA synthesis can be also initiated in the presence of a primer. In addition to standard nucleotides polymerase of this invention also accepts a number of …

Why it's free to use
- Filed October 17, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 17, 2023.
