Abstract
Superoxide dismutase is chemically modified with poly(alkylene oxide), the modified superoxide dismutase having a molecular structure in which both ends of a poly(alkylene oxide) molecule are attached to superoxide dismutase. The modified superoxide dismutase can be used to remove toxic substances derived from oxygen, from the blood circulation in a living body, and has a longer half life in the blood circulation as compared to superoxide dismutase which has not been modified.
