Artificial blood is a colloidal substance, an emulsion carrying a compound of oxygen, electrolytes, plasma expander and some other compounds that act as a buffer. The plasma expander gives volume to the blood. The demand for blood for clinical purposes led to the development of artificial blood. Decades of research led to the discovery of an alternative to human blood by genetic engineering. This genetically engineered hemoglobin (blood) is known as rHB 1.1. It is produced by the process of fermentation and purification of cultivated genetically engineered E.Coli bacteria.
rHB 1.1 is thirty times more effective in the supply of oxygen than natural blood. The risk of contracting dreadful disease by blood transfusion is completely eliminated by the use of artificial blood and it also has a long storage life.
