Description

Application

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

Caution

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

Packaging

1 kg in poly drum

25, 100 g in glass bottle

Preparation Note

Prepared from washed, lysed and dialyzed erythrocytes.

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.

General description

Hemoglobin is the major component of red blood cells, and is responsible for their red color. Its normal concentration in erythrocytes is 34%. Hemoglobin is the most important respiratory protein of vertebrates by virtue of its ability to transport oxygen from the lungs to body tissues, and to facilitate the return transport of carbon dioxide.

Protocols

Enzymatic Assay of Pepsin (3.4.23.1)

This procedure may be used for determination of Pepsin activity using hemoglobin as the substrate. It is a spectrophotometric stop rate determination.

Enzymatic Assay of Proteinase K (EC 3.4.21.64)

This procedure may be used for determination of Proteinase K activity using hemoglobin as the substrate. It is not used to assay the activity of immobilized Proteinase K products, such as Catalog Num...
