Open the CIPO recordAbstract From the Canadian patent
The invention comprises a two-step process for analysis of polynucleotides by chain extension of multiple oligonucleotide primers attached by 5'-linkages to solid supports by first performing PCR of the sample to be analysed in the presence of multiple oligonucleotides in solution the nucleotide sequences of , both sets of oligonucleotides being similar or identical. This produces immobilised single-stranded polynucleotides containing genetic sequence data derived from sample molecules. In a second step support-bound polynucleotides , are interrogated by hybridisation with a single labelled oligonucleotide probe or by second-strand synthesis with a primer-dependent polymerase using an …

Why it's free to use
- Filed March 28, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 28, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 28, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
