Open the CIPO recordAbstract From the Canadian patent
This invention discloses a method of determining differential display of gene expression comprising comparisons of mono-length cRNA libraries. These libraries are probe hybridized to accessible ordered arrays to determine differential hybridization display sites between mono-length segment libraries and to locate genes of expression differential. Also disclosed is a mono-length library corresponding to or complementary with expressed mRNA sequences having cRNA elements 23 nucleotides in length of the formula 5'-gcuggagaucggnnnnnnnnnnn-3', and wherein n represents one of 11 ribonucleotides in sequence corresponding to a complementary 11 nucleotide sequence of the mRNA.

Why it's free to use
- Filed August 26, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 26, 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.
