  • Method for producing hemin proteins using plant cells, resulting proteins and products containing same
    Patent number: 6916787
    Abstract: A method for producing haemin proteins by (i) inserting into plant cells one or more nucleic acid molecules that each comprise at least one sequence coding for a protein component of an animal haemin protein capable of reversibly binding oxygen, or for a variant or portion of said protein component, and optionally a sequence coding for a selection agent; (ii) selecting cells containing nucleic acid coding for the protein component of the haemin protein; (iii) optionally propagating the transformed cells either in a culture or by regenerating whole transgenic or chimeric plants; and (iv) recovering and optionally purifying a haemin protein that includes a complex consisting of the protein or proteins coded for by said nucleic acid and at least one iron-containing porphyritic nucleus, or a plurality of such complexes.

    Date of Patent: July 12, 2005
    Assignees: Institut National de la Sante et de Recherche Medicale, Meristern Therapeutics
    Inventors: Bertrand Merot, Wilfrid Dieryck, Philippe Lenee, Michael Marden, Veronique Gruber, Renee-Josee Pagnier, Sylvie Baudino, Claude Poyart

  • Method for producing human hemoglobin proteins using plant cells
    Patent number: 6344600
    Abstract: A method for producing human hemoglobin proteins by (i) inserting into plant cells one or more nucleic acid molecules that each comprise at least one sequence coding for a protein component of a human hemoglobin protein capable of reversibly binding oxygen, and optionally a sequence coding for a selection agent; (ii) selecting cells containing nucleic acid coding for the protein component of the human hemoglobin protein; (iii) optionally propagating the transformed cells either in a culture or by regenerating whole transgenic or chimeric plants; and (iv) recovering and optionally purifying the human hemoglobin protein that includes a complex consisting of the protein or proteins coded for by the nucleic acid and at least one iron-containing polphyritic nucleus, or a plurality of such complexes.
