Abstract

L'invention concerne un procédé de purification d'érythrocytes, consistant à séparer du sang total par centrifugation, par exemple, pour obtenir une fraction d'érythrocytes et une fraction liquide. Le sang total peut être défibriné ou traité pour éviter qu'il y ait coagulation avant la séparation. De préférence, le sang total est du sang de bovin. Le procédé consiste ensuite à soumettre la fraction d'érythrocytes à une diafiltration pour purifier les érythrocytes. Les érythrocytes purifiés peuvent ensuite être lysés pour former un lysat d'érythrocytes purifiés. Les érythrocytes purifiés et le lysat d'érythrocytes purifiés peuvent être utilisés pour produire un succédané d'hémoglobine.
