A catalytic conformational sensor method for detecting abnormal proteins and proteinaceous particles. The method is based on the interaction of a peptide fragment or probe with an abnormal proteinaceous particle. The interaction catalyzes transformation of the probe to a predominately beta sheet conformation and allows the probe to bind to the abnormal proteinaceous particle. This in turn, catalyzes propagation of a signal associated with the test sample-bound probe. As a result signals can be propagated even from samples containing very low concentrations of abnormal proteinaceous particles. The peptide probes can be designed to bind to a desired peptide sequence or can even be …

Why it's free to use
- Filed May 30, 2002 and granted March 18, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 30, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 30, 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.
