How are hemoglobin based oxygen carriers made?

HBOCs are a type of artificial blood substitute made from molecules of hemoglobin (Hb)—the oxygen-carrying protein in red blood cells—that are either removed from cells and chemically modified during processing into a product, or developed through genetic engineering.

How is hemopure used?

Hemopure is a hemoglobin-based oxygen carrier (HBOC) ready for immediate infusion, that transports and delivers oxygen from the plasma and expands the circulating volume.

What is a hemoglobin based oxygen carrier?

One type of artificial blood substitute that scientists have studied extensively is called a “hemoglobin-based oxygen carrier” (HBOC). HBOCs use the natural oxygen-carrying molecule called hemoglobin (Hb) to carry oxygen throughout the body.

What are synthetic oxygen carriers?

Synthetic oxygen carriers include perfluorocarbons and hemoglobin-based oxygen carriers. These agents effectively transport and deliver oxygen to tissues and have been explored as oxygen carriers in blood-substitute products for purposes such as emergency blood transfusion.

What are the advantages of hemoglobin based oxygen carriers?

Hemoglobin-based oxygen carriers (HBOC) have the potential to increase blood oxygen content in patients with life-threatening anemia in whom red blood cell transfusion is not an option.

Is copper based blood possible?

Unlike most animals on earth, whose blood is iron-based, some mollusks (Mollusca) and arthropods (Arthropoda) have copper-based blood. While the best-known example of an arthropod with copper-based blood is the horseshoe crab, a number of other arthropods have blue blood.

What is Hemopure made of?

Hemopure is made from chemically stabilized, cross-linked cow hemoglobin using a fairly simple and less expensive biotechnology than required for other HBOC blood substitutes. Its minute size – not more than 1/1000 the size of RBCs – is advantageous for transporting oxygen into small spaces between cells.

Why is hemoglobin an effective oxygen carrier?

Hemoglobin: The protein inside red blood cells (a) that carries oxygen to cells and carbon dioxide to the lungs is hemoglobin (b). This is because the hemoglobin molecule changes its shape, or conformation, as oxygen binds. The fourth oxygen is then more difficult to bind.

How do you identify a synthetic oxygen carrier?

Hemoglobin-based carriers can be detected in drug testing with routine laboratory tests based on the detection of free hemoglobin. Perfluorocarbon is not metabolized by the body and exhaled through the lung and can be measured with chromatography.

How much does artificial blood cost?

Hospitals can buy blood for as little as $50 a unit at times but the total costs have been estimated to run at about $175 to $200 a unit, not counting the cost of deaths and disease arising from misuse.
