Yuji Iwashita, Katsumi Ajisaka: Blood substitute containing modified hemoglobin. Ajinomoto Company Incorporated, Oblon Fisher Spivak McClelland & Maier, November 17, 1981: US04301144 (419 worldwide citation)

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 circulati ...
