Open the CIPO recordAbstract From the Canadian patent
A method for producing proliferating cultures of dendritic cell precursors is provided. Also provided is a method for producing mature dendritic cells in culture from the proliferating dendritic cell precursors. The cultures of mature dendritic cells provide an effective means of producing novel T cell dependent antigens comprised of dendritic cell modified antigens or dendritic cells pulsed with antigen, including particulates which antigen is processed , and expressed on the antigen-activated dendritic cell. The novel antigens of the invention may be used as immunogens for vaccines or for the treatment of disease. These antigens may also be used to treat autoimmune diseases such …

Why it's free to use
- Filed April 1, 1993 and granted May 24, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2013.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
