Method for producing human hemoglobin proteins using plant cells

摘要

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.
