    Abstract: 본발명은바이오마커로서부위특이적으로 N-당쇄화된당펩타이드를이용하여바이오마커의 N-당쇄변화를탐지하는방법에관한것이다. 좀더 구체적으로, 본발명에서는비특이적단백질분해효소를이용하여혈액의햅토글로빈을펩타이드와당펩타이드로분해하였으며, 207번과 211번등 총 4개의 N-당쇄화부위를가진당펩타이드만을분리하였다. 본발명자들은이렇게얻은 4개의 N-당쇄화부위에결합된당펩타이드를이용하여종양특이적바이오마커를발굴함으로써고특이적이고고감도인종양의 N-당쇄변화를탐지하는방법을발명하기에이르렀다.

    Abstract: The present invention relates to a method to diagnose gastric cancer by detecting the changes in the sugar chain, and to a kit to diagnose gastric cancer and, more specifically, to a method to diagnose gastric cancer based on the reduction of a high mannose structure of an N-sugar chain compared with a normal person in case of increasing fucosylation of an N-linked glycosylation of haptoglobin derived from a gastric cancer patient detected by a lectin or weight analysis method; and increasing or practically changing the structures of the specific sugar chain in accordance to an antennary division using a lectin or a weight analysis method as a diagnosis while the detected N-sugar chain structures uses lectin or weight analysis method as a diagnosis marker, and to a kit diagnosing gastric cancer.
