Open the CIPO recordAbstract From the Canadian patent
A method for staining a Pap test slide specimen for conventional Pap test and particularly a ThinPrep Pap test specimen in which a number of multiple , hydrating staining and dehydrating step are performed in an equal number of 10 to 15 dippings at about equal dip times of about 1 second. The total method time is 100 to 150 seconds. The specimen pre-staining fixative solution is a 10% buffered formalin solution and a 95% lower alcohol in a 1:2 volumetric ratio. The method simplifies the staining process and laboratory technician error, while providing an improved stain contrast with a clean background in the resultant conventional and ThinPrep pap test stained specimens.

Why it's free to use
- Filed August 7, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 7, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 7, 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.
