Open the CIPO recordAbstract From the Canadian patent
In accordance with the present invention it has been discovered that chimeric receptors comprising at least the ligand binding domain of a member of the steroid/thyroid receptor protein superfamily having incorporated therein the DNA binding domain of the yeast GAL4 protein are capable of forming functional homodimers. Such homodimers are useful for example, in assays to determine the ligand for an orphan member of the steroid/thyroid superfamily of receptors for identifying compounds which are selective for a specific steroid/thyroid receptor protein from among a plurality of such receptors which respond to a common ligand and the like.

Why it's free to use
- Filed December 29, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 29, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 29, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
