Open the CIPO recordAbstract From the Canadian patent
An amino acid sequence that can specifically introduce a mucin type sugar chain into a protein or peptide chain and a technique of introducing a mucin type sugar chain into protein or peptide by utilizing such a sequence are disclosed. GalNAc moiety of UDP-GalNAc (where UDP represents uridine 5'-diphosphate and GalNAc represents N-acetylgalactosamine) is introduced into the amino acid X(O) in the presence of UDP-GalNAc: polypeptide .alpha.1 O-GalNAc transferase (O-GalNAc T):, X(-1) - X(0 - X(1) - X(2) - X(3) (I) where X(-1) and X(2) represent independently any amino acid, X(0) represents T or S and X(1) and X(3) represent independently any amino acid except that at least one of X(1) and …

Why it's free to use
- Filed November 1, 1995 and granted March 18, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 1, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 1, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
