Shipping Method: Shipped on ice packs (blue ice)

Background Information

Haptoglobin is a glycoprotein primarily synthesized by the liver and belongs to the positive acute-phase proteins. It binds free hemoglobin, preventing it from causing kidney damage and iron loss in the circulatory system. The expression level of this protein is closely related to hemolysis, liver function, inflammatory responses, and associated metabolic diseases. It is an important molecule in research areas such as inflammation, diabetic nephropathy, coronary artery disease, and malaria infection.
