Open the CIPO recordAbstract From the Canadian patent
Disclosed is an apparatus and method for the rapid flowthrough assay of an analyte. A multiplicity of binding sites which bind selectively to an analyte are immobilized on a rigid matrix which, defines a flowpath. A liquid sample containing the analyte is delivered convectively to a hydraulically full volume through the matrix to permit formation of a binding site: analyte complex. A detectable tagging reagent capable of binding with the binding site or the complex is then delivered convectively to the matrix and the amount of tagging reagent which is bound is detected to provide an assay of the concentration or presence of the analyte.

Why it's free to use
- Filed March 26, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 26, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 26, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
