| 摘要 |
The present invention relates to pharmaceutical compositions of transferrin and to the manufacture of such preparations. The present invention concerns specifically a pharmaceutical composition of apotransferrin, the iron-free form of transferrin, wherein the composition has at least 90% of the theoretical iron binding capacity of iron-free transferrin, contains less than 3% transferrin dimers and no detectable transferrin polymers or aggregates, and has an iron-saturation of less than 5%. The pharmaceutical apotransferrin composition of this invention effectively binds non-transferrin-bound-iron to a harmless form when administered as an intravenous injection or infusion to patients. The pharmaceutical composition of this invention does not contain viruses, denatured forms of transferrin or other harmful components.
