  • Antibodies directed against the alpha interferon receptor
    Patent number: 5886153
    Abstract: The present invention relates to antibodies against an alpha interferon receptor, as well as to kits comprising such antibodies. The antibodies of the invention are suitable for the assay of the receptors or for their visualization in the case of imaging. The present antibodies and kits can thus be used as diagnostics or imaging agents, or as pharmacological models to test compounds derived from human alpha interferon.

    Patent number: 5731169
    Abstract: The invention relates to the human alpha interferon receptor and to the DNA sequence, including the cDNA sequence, encoding the receptor. The invention also relates to non-human cells which express said receptor, to a process for obtaining said cells, and to a process for the preparation of the receptor.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: March 24, 1998

  • Manufacture of interferon
    Patent number: 3951740
    Abstract: This invention relates to the production of interferon. In accordance with the present invention, interferon is produced by growing a continuous cell line in a suspension culture, the cells first being primed by cultivation in the presence of interferon specific to the cells and L-glutamine, interferon production being initiated by contacting the cells with a high concentrated suspension of virus inducer, then removing the virus and incubating the cells in a nutrient medium. Concentration and purification to give interferon preparations can be effected by known methods. Various types of interferon preparations of high titre have been produced on an industrial scale.
