Artificial blood research. Masked technicians work to extract haemoglobin from out-of-date human blood. Haemoglobin is being tested for use as a type of artificial blood. The technicians work through the gloves of an isolator in a sterile laboratory. Haemoglobin is a protein that colours blood red, and it carries gases (carbon dioxide & oxygen) to and from the lungs. Low blood reserves worldwide and a high demand for blood has led to research to produce artificial blood. Artificial blood can serve any blood group, is free of blood- borne diseases, and has an increased shelf-life. Photographed at Baxter in Lessines, Belgium.
