Combined the globin (haptoglobin, HP)

Also known as haptoglobin, with a molecular weight of 85,000 acid glycoprotein, widely present in the serum and other body fluids of humans and a variety of mammals. CAM electrophoresis and agarose gel electrophoresis, haptoglobin in α2 zones, in the molecule, there are two pairs of peptide chain (α chain and β chain) together form α2β2 tetramer. Haptoglobin primarily synthesized in the liver, its degradation also liver, the half-life of about 3.5 to 4 days.
