General description
Native α1-acid glycoprotein from human plasma. Glycoprotein used for the study of the structure of oligosaccharide units. Consists of 40 - 45% carbohydrate. Present in human plasma at concentrations of 55 - 140 mg/100 ml. Clinically,α1-AG is an acute-phase reactant that, together with haptoglobin, indicates acute inflammation. Selectively suppresses the augmentation of NK cell activity by IFN-α and IFN-γ. Theα1-AG:α1-antitrypsin ratio is useful in diagnosis of liver disease. A sialic acid-deficientα1-AG has been observed in serum or urine of patients with Hodgkin’s disease, psoriatic arthritis, diabetes, and chronic myeloid leukemia. Sialic acid-deficientα1-AG has an affinity for vitamin B12.
