A reagent composition adapted to be coated onto a support surface in order to provide that surface with a high density of reactive groups. The surface thus , coated, can be used for any suitable purpose and is particularly well suited , for use as a solid phase synthesis support surface. The synthesis support surface, in turn, can be used in repetitive and combinatorial syntheses such as the synthesis of polynucleotides, polypeptides and polysaccharides. The polymeric coating can be used to provide increased effective surface area particularly in situations in which the effective area of the support surface is itself limited, as on the surface of a silicon wafer. In so doing the , …

Why it's free to use
- Filed February 6, 2001 and granted July 17, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 6, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 6, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
