Open the CIPO recordAbstract From the Canadian patent
Methods for determining whether a biological macromolecule binds to a compound. The methods comprise the steps of: a) obtaining an FT-IR spectrum of a solution comprising a biological macromolecule and obtaining an FT-IR spectrum of a solution comprising a compound; b) obtaining an FT-IR spectrum of a solution comprising a mixture of the biological macromolecule and the compound; c) subtracting the FT-IR spectrum of the individual biological macromolecule and compound from the FT-IR spectrum of the mixture to determine a subtracted index; and d) identifying a compound that binds to the biological macromolecule when the subtracted index of step c) is not equal to about 0.

Why it's free to use
- Filed November 9, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 9, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 9, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
