Open the CIPO recordAbstract From the Canadian patent
A method, composition device, apparatus, and kit for the, determination of the presence or amount of an analyte by monitoring an analyte-mediated ligand binding event in a test mixture which contains the analyte to be assayed, a specific binding member a, Raman-active label, and a particulate having a surface capable of inducing a surface-enhanced Raman light scattering. The test mixture is illuminated with a radiation sufficient to cause the Raman-active label in the test mixture to emit a detectable Raman spectrum. The differences in the detected surface-enhanced Raman scattering spectra are dependent upon the amount of the analyte present in the test mixture. Thus, by monitoring these …

Why it's free to use
- Filed September 9, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 9, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 9, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
