Open the CIPO recordAbstract From the Canadian patent
Synthetlc peptides are described having an amino acid sequence corresponding to that of the T epitopes of tetanus toxin and their analo0s able to be recognised by different human T cell clones in a association with a wide range of alleles of the human major histacompatibillty complex (MHC). Said peptides can be used as universal carriers in the preparation of immunogenic conjugates consisting of said peptides and a natural or synthetic hapten derived from a pathogenic agent of interest. The immunogenic conjugates are particularly suitable for preparing synthetic vaccines able to provide a protective immunity against different pathogenic agents which is not genetically restricted or is only …

Why it's free to use
- Filed December 27, 1989. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 27, 2009.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 27, 2011.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
