PEPTIDE MARKER FOR CANCER DIAGNOSIS, AND CANCER DIAGNOSIS METHOD USING SAME

摘要

The present invention relates to a peptide marker for cancer diagnosis and a cancer diagnosis method using the same, more precisely to a peptide marker for cancer diagnosis screened by the following steps: separating and concentrating glycoproteins including a certain glycan chain related to the occurrence of cancer; hydrolyzing the glycoproteins to obtain polypeptides; and quantitatively analyzing the polypeptides to identify certain polypeptides that can track quantitative changes in glycoproteins glycosylated in a specific manner by the occurrence of cancer, and to a cancer diagnosis method using the said peptide marker.
