Method for clinical examination based on the structures of immunoglobin G-linked oligosaccharides

摘要

The present invention relates to a novel clinical examination method which comprises analyzing the alteration in the amount of a specific component in oligosaccharides of immunogloblin G. Human diseases such as liver diseases, malignant hypertension, immunogloblin A-nephropathy, pediatric disorders, etc., are examined in terms of the alteration in bisecting N-acetylglucosamine-containing oligosaccharides in immunogloblin G from collected humor. The present invention provides highly accurate information in a manner applicable to practical operation for examination of liver diseases, allergic diseases, malignant hypertension, immunogloblin A nephropathy, pediatric disorders, as well as aging-dependent variations and the therapeutic effect of interferon.
