Anti-Hemoglobin [Clone HB11-203.1] - 1.0 mg

Hemoglobin is the iron-containing oxygen-transport metalloprotein in red blood cells of all vertebrates as well as in the tissues of some invertebrates. In mammals, hemoglobin makes up about 35% of the total content of red blood cells. It has an oxygen-binding capacity of 1.34 mL O2 per gram, which increases the total blood oxygen capacity seventy-fold compared to dissolved oxygen in blood. The mammalian hemoglobin molecule can bind up to four oxygen molecules. Hemoglobin also carries some of the body's respiratory carbon dioxide (about 20–25% of the total) as carbaminohemoglobin as well as nitric oxide bound to a thiol group, releasing it at the same time as oxygen. Other cells that contain hemoglobin include the A9 dopaminergic neurons in the substantia nigra, macrophages, alveolar cells, and mesangial cells in the kidney. In these tissues, hemoglobin has a non-oxygen-carrying function as an antioxidant and a regulator of iron metabolism.
