Native Human Haptoglobin

• Cat.No.: HP-4387H
• Product Overview: Human HP produced from pooled human plasma corresponding to the Mw of isotypes of HP at 86kD and 200kD.

Specification

• Description: HP is a glycoprotein which is synthesized in the liver and circulates in the blood. HP is produced typically by hepatocytes but also by other tissues: e.g. skin, lung, and kidney. It is a positive acute phase protein that binds free hemoglobin and removes it from the circulation to prevent kidney injury, and iron loss following hemolysis. The HP-hemoglobin complex is subsequently removed by the reticuloendothelial system (generally the spleen). As the reticuloendothelial system removes the HP-hemoglobin complex from the body, HP levels are reduced in hemolytic anaemias. In the course of binding hemoglobin, HP sequesters the iron inside hemoglobin, preventing iron-utilizing bacteria from benefitting from hemolysis.
