A blood-substitute comprising of from about 5 to about 25 grams of crosslinked hemoglobin per deciliter of an aqueous pharmaceutically acceptable carrier medium, said blood-substitute being substantially free of cell stroma, non-hemoglobin proteins and pyrogens and said blood-substitute being suffic...
