Gene Information

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.

Application

Hemoglobin from porcine was used to test the role of the L-arginine/nitric oxide pathway in relaxation of isolated human penile cavernous tissue and circumflex veins. It was also used to study the role of nitric oxide in neurogenic vasodilation of porcine cerebral artery.

Packaging

1 g in poly bottle

Biochem/physiol Actions

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.
Oxygen transporter, NO scavenger

Caution

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

We employ a clinical multiphoton microscope to monitor in vivo and noninvasively the changes in reduced nicotinamide adenine dinucleotide (NADH) fluorescence of human epidermal cells during arterial occlusion. We correlate these results with measurements of tissue oxy- and deoxyhemoglobin concentration during
