Open the CIPO recordAbstract From the Canadian patent
A method for detecting blood component in a sample comprising reacting a human erythrocyte membrane band 3 glycoprotein (band 3) in the sample and a hemagglutinin produced by a microorganism belonging to the genus Conidiobolus (CA) and measuring said band 3 glycoprotein contained in a complex produced by the reaction. Because band 3 can be detected specifically, at high sensitivity and stably by the use of CA, the method ensures qualitative or quantitative, and accurate detection of human blood component in feces or contents of digestive organs, of which the determination of the presence or quantity of human blood component by hemoglobin is difficult.

Why it's free to use
- Filed December 27, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 27, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 27, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
