General description

α-1-Acid glycoprotein (AGP)/orosomucoid (ORM), a glycoprotein has a molecular weight of 41-43kDa. It is considered as one of the important acute phase proteins in humans and rats. AGP may belong to the lipocalin family.

Application

α1-Acid glycoprotein from human plasma has been used:
  • as negatively charged protein to investigate the adsorption processes onto the surface of polyelectrolyte multilayers
  • to incubate plates coated with purified antiserum in the study to investigate its serum concentration by ELISA
  • to study the effect of its different concentrations on the antiviral activity of human immunodeficiency virus (HIV) protease inhibitors

Biochem/physiol Actions

α1-Acid glycoprotein possesses immunomodulating effects. It has the ability to bind to acidic drugs, like phenobarbital.
