Open the CIPO recordAbstract From the Canadian patent
The presence of alloantigen alleles or antibodies to alloantigen alleles is determined by employing a support to which alloantigen alleles are bound, and combining a specimen which contains either the alloantigen alleles or antibodies to alloantigen alleles with a reagent comprising antibodies to the alloantigen allele(s) of interest. By combining the specimen reagent and support, and, determining the amount of antibody which binds to the support as compared to a negative control, the presence of the alloantigen antigen or anti-alloantigen is related to a reduced amount of antibody binding to the support. The amount of antibody may be determined by any convenient assay.

Why it's free to use
- Filed December 9, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 9, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 9, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
