Open the CIPO recordAbstract From the Canadian patent
Neurotransmission by excitatory amino acids (EAAs) such as glutamate is mediated via membrane-bound surface receptors. DNA coding for one family of these receptors of the kainate binding type of EAA receptors has now, been isolated and the receptor protein characterized. Herein described are recombinant cell lines which produce the EAA receptor as a heterologous membrane-bound product. Also described are related aspects of the invention, which are of commerical significance. Included is use of the cell lines as a tool for discovery of compounds which modulate EAA receptor stimulation.

Why it's free to use
- Filed August 26, 1992 and granted April 10, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 26, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 26, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
