Open the CIPO recordAbstract From the Canadian patent
Current techniques for the diagnosis of liver fluke infection in animals involve examination of faecal matter for parasite eggs and as such are difficult to use outside a research environment. The invention provides an antibody-binding region of a liver fluke tegument protein comprising a peptide with an amino-acid sequence: Asparagine-Lysine-Glutamic acid-Glycine-Glutamic acid-Proline-Glutamic acid as well as antibodies raised against it. Either the antibody-binding sequence or antibodies raised against it can be used in a test system for the diagnosis of liver fluke infection.

Why it's free to use
- Filed August 16, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 16, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 16, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
