Description

Native alpha1-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, alpha1-AG is an acute phase reactant that, together with haptoglobin, indicates acute inflammation. Selectively suppresses the augmentation of NK cell activity by IFN-alpha and IFN-gamma. The alpha1-AG:alpha1-antitrypsin ratio is useful in diagnosis of liver disease. A sialic acid-deficient alpha1-AG has been observed in serum or urine of patients with Hodgkin's disease, psoriatic arthritis, diabetes, and chronic myeloid leukemia. Sialic acid-deficient alpha1-AG has an affinity for vitamin B12., Native alpha1-acid glycoprotein from human plasma. Glycoprotein used for the study of the structure of oligosaccharide units.
