Homogeneous Preparations of Chimeric Protein

摘要

Variant forms of chimeric protein molecules comprising a Factor VII moiety and an Fe region of an IgG1 moiety provide improved properties. The variants are more resistant to proteolytic degradation. Thus preparations of the variant forms are more homogeneous and have a longer half-life. The variant forms are used for treating cancer, atherosclerosis, psoriasis, diabetic retinopathy, wet macular degeneration, and rheumatoid arthritis.
