Hemoglobin to come from cows

Researchers from the Texas Tech University Health Sciences Center and HemoBioTech, Inc., have come up with a hemoglobin product, HemoBioTech, to make blood substitutes in humans.

Hemoglobin is a protein produced by red blood cells. It delivers oxygen to the body from the lungs.

HemoBioTech comes from antelope, bison, and cattle. Unlike blood cells in humans, this product is free of HIV and hepatitis, although patients run the risk of contracting mad cow disease.

HemoBioTech may serve as an alternative to current stocks of donated blood. Researchers plan on performing clinical trials with HemoBioTech in 2008.
