Abstract From the Canadian patent

This invention relates to polypeptides that are human somatomedin carrier protein subunits and to processes for producing them. The carrier protein subunits bind to human somatomedin-like polypeptides, also known as insulin-like growth factors. The process involves preparation from a human serum fraction, Cohn IV-1, by a molecule of various chromatographic steps. This invention also relates to DNA molecules encoding human somatomedin carrier protein-like polypeptides, recombinant DNA molecules hosts, processes, for producing carrier protein-like polypeptides human, somatomedin carrier protein-like polypeptides produced using those molecules, hosts and processes. The invention relates to DNA …

Why it's free to use

  • Filed December 21, 1989 and granted August 1, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 21, 2009.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 21, 2011.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
