N-glycans analysis workflow at NFML

글리코실화(탄수화물이 거대분자에 부착되는 현상)는 다양한 생체 분자의 기능을 조절하는 데 중요한 역할을 합니다. 글리코실화는 분자가 각각의 기능을 수행하는 방식에 영향을 미치고 음식은 유리 탄수화물과 당접합체를 모두 포함하기 때문에 주요 생물학적 시스템에서 유리 탄수화물 뿐만 아니라 글리칸 잔기의 유형, 구조 및 양을 밝히는 것은 영양, 질병 진단, 모니터링 및 치료에 큰 의미가 있습니다. NFML은 LC MS/MS 및 글리코정보학 접근법을 모두 사용하여 다양한 바이오 샘플에서 글리칸을 식별, 특성화 및 정량화합니다. 이에 대한 우리의 주요 초점은 예후 및 진단 바이오마커를 모두 발견하는 것이고 다양한 시스템과 유기체에 걸쳐 글리코실화가 세포 기능에 미치는 영향에 대한 중요한 생물학적 정보를 제공하는 다양한 생체 재료의 글리칸을 프로파일링하고 특성화하기 위해 노력해 왔습니다. 이에 대한 우리의 주요 협력자는 AGRS입니다.
