Description

General description

Hemoglobin is present in the red-blood corpuscles (RBCs) of vertebrates. It is composed of a globular structure with four α-β sub-units.

Application

Hemoglobin from bovine blood has been used as a supplement in tryptone yeast extract salts and glucose (TYESG) agar for performing extracellular proteolytic activity of Flavobacterium psychrophilum. It has also been used as a standard in Raman spectrometry.

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

Biochem/physiol Actions

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.

Packaging

1 piece contains 100 g hemoglobin powder

Caution

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