Open the CIPO recordAbstract From the Canadian patent
The present invention relates to a system and methods for identifying differential peptide expression in one or more peptide populations. Each population 109 is labeled with a discernable label and provides a mechanism to resolve mixed peptide populations 130 using mass spectroscopy-based techniques. Spectra 146 produced by the peptide sample are used to interrogate a spectral database in which peptide sequences of known spectra are stored. In addition to providing sequence information the methods presented herein may , be used to determine qualitative and quantitative measurements of peptide expression. These measurements may further be used to determine proteomic differences and …

Why it's free to use
- Filed July 12, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 12, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 12, 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.
