Abstract
A novel modified hemoglobin was prepared. The hemoglobin is coupled with a polyalkylene glycol or its derivative, and the products are useful as a blood substitute. The oxygen-carrying capacity of this hemoglobin is nearly equal to that of a native hemoglobin, and the residence time in the circulation is satisfactorily long.
