Abstract From the Canadian patent

Disclosed is a method for determining the number of repeat units in a repeat region of a target nucleic acid. The method comprises a discontinuous primer extension reaction wherein a primer is extended in discrete increments corresponding to a single repeat unit. Following each increment of primer extension, a detection step is performed in which a modulation in a signal is detected when the primer has been extended by an amount equal to the total length of a repeat region. By counting the number of increments of discrete primer extension required to cause a modulation in the signal the number of , repeat units making up the repeat region is determined. In the method a , plurality of …

Why it's free to use

  • Filed December 1, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 1, 2019.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 1, 2021.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
