Open the CIPO recordAbstract From the Canadian patent
Cellophane wrapping (CW) of hamster pancreas induces proliferation of duct epithelial cells followed by endocrine cell differentiation and islet neogenesis. Using the mRNA differential display technique a cDNA clone expressed in cellophane wrap but not in control pancreata was identified. Using this cDNA as a probe, a cDNA library was screened and a gene not previously described was identified and named INGAP.

Why it's free to use
- Filed February 12, 1996 and granted December 3, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 12, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 12, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
