Abstract From the Canadian patent

The present invention provides methods of modifying in vivo mutagenesis or homeologous recombination in a eukaryote. The method of modifying in vivo mutagenesis involves transforming a eukaryote with a nucleotide sequence capable of expressing a wild-type prokaryotic MutS MutL, MutH, MutU, NLS-, MutS, NLS-MutL NLS-MutH, NLS-MutU protein, or a combination thereof and , expressing the protein. A method of modifying recombination between homeologous chromosomes in an allopolyploid eukaryotic organism comprising expressing a nucleotide sequence encoding prokaryotic NLS-MutS in combination with one or more than one of NLS-MutL, NLS-MutH NLS-MutU, within a germ cell , of the allopolyploid …

Why it's free to use

  • Filed June 6, 2003 and granted February 26, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 6, 2023.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 6, 2025.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
