METHOD FOR IDENTIFYING BLOOD-DERIVED GLYCOPROTEIN USING SPECIFIC LECTIN AFFINITY CHROMATOGRAPHY

摘要

The present invention relates to a method for detecting glycoprotein which reveals changes of glucides in oncogenesis and metastasis in the blood in individuals undergoing diagnosis. More specifically, the present invention relates to: a method for finding glycoprotein by a mass spectrographic method using a specific type of N-linked sugar chain found in glycoproteins, which is known to play a role in oncogenesis and metastasis; and a cancer-diagnosing kit.
