Open the CIPO recordAbstract From the Canadian patent
Oligopeptides having an amino acid sequence corresponding to a receptor's extracellular domain, and having sequence similarity to regulatory peptides from MHC class I antigens, enhance the physiological response of ligand binding to the corresponding receptor. The oligopeptides are used in diagnosis and therapy of diseases that involve inadequate or inappropriate receptor response as well as in the screening of drug candidates that affect surface expression of receptors. Also useful for drug screening is a modified receptor molecule, where the sequence corresponding to the regulatory peptide is modified or deleted.

Why it's free to use
- Filed March 7, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 7, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 7, 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.
