Open the CIPO recordAbstract From the Canadian patent
A method is disclosed for automated multiplex sequencing of DNA with an integrated system. This system comprises a hybridization chamber for a membrane containing size-fractionated multiplex sequencing reaction products apparatus for fluid delivery to the chamber imaging apparatus for image recording of fluorescence emanating from the membrane and programmable controller apparatus for controlling operation of the system. The multiplex reaction products are hybridized with a probe then an enzyme is bound to the probe, and a fluorogenic substrate is introduced into the chamber by the fluid delivery apparatus. The enzyme converts the fluorogenic substrate into a fluorescent product which, when …

Why it's free to use
- Filed October 18, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 18, 2014.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
