ABSTRACT:
A chemically modified, crosslinked hemoglobin product suitable for use as a hemoglobin based oxygen carrier comprises a mixture of hemoglobin species and consists essentially of about 40% tetrameric hemoglobin units of molecular weight about 64,000 daltons, up to 5% dimeric hemoglobin units of molecular weight about 32,000 daltons, and the balance oligomeric hemoglobin units of molecular weight up to about 60,000 daltons, the mixed product containing no polymeric hemoglobin species of molecular weight greater than 600,000 daltons. The product can be made directly by a crosslinking reaction under controlled conditions, without the need for separating therefrom high molecular weight species.
