CANCER DIAGNOSIS MARKER USING THE ABERRANT GLYCOSYLATION OF A PROTEIN

摘要

The present invention relates to a method for diagnosing cancer using information on the aberrant glycosylation of a glycoprotein. More particularly, the present invention relates to a cancer diagnosis peptide marker which is screened by: a step of separating, using a lectin, a glycoprotein which is aberrantly glycosylated in accordance with the occurrence of cancer; and a step of selecting a hydrolyzed peptide marker derived from the aberrantly glycosylated glycoprotein using the quantitative change in the separated glycoprotein. The present invention also relates to a method for diagnosing cancer using the peptide marker as an agent.
