Abstract From the Canadian patent

Abstract of the Disclosure, A method for the detection of a specific nucleic acid sequence of a predetermined nucleic acid in a specimen includes the use of oligonucleotide primers complementary to the sequence, a labeled probe and known amplification techniques to form primer extension products of the primers. At least one of the primers is labeled with a specific binding moiety which, at some point in the method is, complexed with a receptor thereto. The receptor is bound to a solid support material, such as polymeric particles. The complexation can occur either prior or subsequent to the formation of primer extension products. Thus, the detectable complex is captured on the solid support …

Why it's free to use

  • Filed November 2, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 2, 2009.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 2, 2011.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
