Open the CIPO recordAbstract From the Canadian patent
This invention relates to hydrolase fluorogenic substrates with improved cell permeability, methods for the preparation thereof and methods of measuring , activities of hydrolases particularly in cell-based assays. The substrates easily diffuse into the cells, where they are enzymatically processed to yield photostable fluorescent products, and are particularly fitted for visualising enzyme-derived activities in cell-based assays.

Why it's free to use
- Filed December 26, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 26, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 26, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
