Abstract From the Canadian patent

Methods of nucleic acid amplification with external controls are provided that verify the absence or presence of specific target sequences and correct , primers and probes. A single-stranded external control polynucleotide is , amplified with primers of the same sequence as target primers. Probes with detectable labels and sequences specific for target and external control polynucleotides allow for detection and measurement. The primers and the detectable probe are adjacent or substantially adjacent when hybridization of a self-quenching probe complementary to both target and external control polynucleotides. A kit of PCR reagents can be dispensed into vessels for rapid and accurate …

Why it's free to use

  • Filed August 23, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 23, 2021.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 23, 2023.
