Abstract From the Canadian patent

Use of the ssrA gene or tmRNA, an RNA transcript of the ssrA gene or , fragments thereof as target regions in a nucleic acid probe assay for the detection and identification of prokaryotic and/or eukaryotic organisms is described. Nucleotide sequence alignment of tmRNA sequences from various organisms can be used to identify regions of homology and non-homology within the sequences which in turn can be used to design both genus specific and species specific oligonucleotide probes. These newly identified regions of homology and non-homology provide the basis of identifying and detecting organisms at the molecular level. Oligonucleotide probes identified in this way can be used to …

Why it's free to use

  • Filed May 15, 2000 and granted April 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 15, 2020.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 15, 2022.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
