摘要： Red blood cells are purified by separating whole blood, such as by centrifugation, to form a red blood cell fraction and a liquid fraction. The whole blood can be defibrinated or treated to prevent coagulation prior to separation. Preferably, the whole blood is bovine blood. The red blood cell fraction is then diafiltered to purify the red blood cells. The purified red blood cells can then be lysed to form a lysate of purified red blood cells. The purified red blood cells and the lysate of purified red blood cells are suitable for use in producing hemoglobin blood substitute.

摘要： A method for producing a stable polymerized hemoglobin blood-substitute from blood. The method of this invention includes mixing blood with an anticoagulant to form a blood solution, washing the red blood cells in the blood solution and then separating the washed red blood cells from the white blood cells. This method also includes disrupting the red blood cells to release hemoglobin and form a hemoglobin solution, which is then treated by high performance liquid chromatography to form a hemoglobin eluate. The hemoglobin eluate is then deoxygenated, contacted with a first sulfhydryl compound to form an oxidation-stabilized deoxygenated hemoglobin solution, and mixed with a cross-linking agent to form a polymerization reaction mixture, which is then polymerized. The polymerized hemoglobin solution is then diafiltered with a physiologic solution and with a sulfhydryl compound, whereby the polymerized hemoglobin solution is made physiologically acceptable, and whereby the sulfhydryl compound scavenges oxygen, to form a stable polymerized hemoglobin blood-substitute.

摘要： Red blood cells are purified by defibrinating whole blood and then filtering the defibrinated whole blood, whereby at least a portion of a plasma component is separated from the red blood cells to form a suspension of red blood cells, thereby purifying the red blood cells. Whole blood is defibrinated by, for example, using a chemical coagulating agent or mechanical agitation. Separation of the plasma component from red blood cells can be completed by, for example, diafiltration. The suspension of red blood cells can then be employed to produce a hemoglobin-based oxygen carrier.
