It is intended to provide novel mutant RNA polymerases enabling a transcriptional sequencing method whereby a high SN ratio can be achieved in sequence analysis with the use of capillary and longer and more accurate base sequencial data can be obtained by a single reaction. More specifically a , mutant RNA polymerase derived from a wild type RNA polymerase by substitution of at least one amino acid and deletion of at least one amino acid or a , mutant RNA polymerase derived from a wild type RNA polymerase by deletion of at least one amino acid, wherein the above-described substitution and/or deletion of amino acid(s) have been performed so that the resultant mutant RNA polymerase has …

Why it's free to use
- Filed June 7, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 7, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
