Description générale

Hemoglobin (Hb) is the protein responsible for storage and transport of oxygen and other gaseous ligands in red blood cells (RBC). Hb is also the pioneer material for synthesis of Hb-based oxygen carriers (HBOCs) that can be used as substitutes for RBC.

Application

The solubility of α-elastin has been applied to construction of elastin-mimetic biomaterials.

Actions biochimiques/physiologiques

Oxygen transporter. The Fe2+/Fe3+ balance is a physiological indicator of blood oxygenation; deoxygenated hemoglobin accessorizes a feedback loop by reducing nitrite to NO, a vasodilator which enhances blood flow to oxygen-deprived tissues.

Attention

Since native hemoglobin is readily oxidized in air, these preparations may be predominantly methemoglobin.

Hemoglobin-based oxygen carriers (HBOC) are currently being developed as red blood cell (RBC) substitutes for use in transfusion medicine. Despite significant commercial development, late stage clinical results of polymerized hemoglobin (PolyHb) solutions hamper development. We synthesized two types of PolyHbs
