The present invention makes available a rapid effective assay for screening , and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular protein e.g. a , receptor or ion channel. The subject assay enables rapid screening of large numbers of compounds to identify those which act as an agonist or antagonist to the bioactivity of the cellular protein. The subject assay is particularly amenable for identifying surrogate ligands for receptors especially from small molecule or peptide libraries or from peptides produced by an autocrine system. Identification can be achieved via activation of a yeast signalling pathway, …

Why it's free to use
- Filed September 24, 1997 and granted December 9, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 24, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 24, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
