Open the CIPO recordAbstract From the Canadian patent
A method for testing whether or not an antibody that binds with any of a plurality of target antigens is contained in a test sample. In this method, a test sample is contacted with an antigen microarray having spots of at least eight types of target antigens. In the case the test sample contains an antibody corresponding to the target antigens that antibody is retained on the antigen microarray by an antigen-antibody reaction. A labeled secondary antibody labeled with a fluorescent pigment is then contacted with the antigen microarray. Fluorescence of the labeled secondary antibody is then detected by a detection device such as a laser fluorescent microscope or laser scanner.

Why it's free to use
- Filed June 19, 2002. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 19, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 19, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
