DNA strands having the ability to biotechnologically produce glycerol-3-phosphate acyltransferase (ATase) useful for converting the property of the PG of membrane lipids into that of more chilling resistance, specifically a chimeric gene of glycerol-3-phosphate acyltransferase (ATase) cDNA derived from squash in which the about onethird central region (the site cleaved by Kpn I and Hind III) has been replaced with the corresponding region of spinach ATase cDNA, a cDNA derived from squash in which the about one-sixth central region (the site cleaved by Hind III and Sac I) has been replaced with the corresponding region of spinach ATase cDNA, or a chimeric gene of ATase cDNA, derived from …

Why it's free to use
- Filed July 3, 1996 and granted May 13, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended July 3, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 3, 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.
