Open the CIPO recordAbstract From the Canadian patent
The present invention relates to the field of nucleic acid sequence analysis. The invention provides methods for performing a polymerase signal assay (PSA) to analyze nucleotide sequences using solid phase sequence arrays comprising a plurality of sequence reagents with primer sequences 4-6 bases in length. The methods of the invention generate a binary signal pattern which can be used to identify nucleic acid sequences and/or mutations and polymorphisms of a nucleic acid sequence. Mutations and polymorphisms which can be identified by the methods of the invention include single nucleotide polymorphisms (SNP's) base deletions, base insertions, and heterozygous as well homozygous …

Why it's free to use
- Filed June 15, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 15, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 15, 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.
