摘　要：摘　要：糖链是重要的生物信息分子，在许多生理和病理过程中都发挥着独特作用。糖链结构非常复杂，具有微观不均一性，其分析和结构解析一直是糖生物学研究的瓶颈。质谱具有灵敏度高、可获得多种结构信息和适于分析混合物等优点，是糖链定性定量分析的一种理想手段。电喷雾电离质谱和基质辅助激光解析电离质谱两大生物质谱技术已被广泛应用于糖链的相对分子质量指纹谱分析、序列和连接方式测定及相对定量分析。对近年来以质谱为主要分析手段的糖链分析方法研究进展做一综述。

Abstract: Abstract: As a group of bioinformation molecules， glycans play significant roles in many physiological and pathological processes. Due to their structural complexity and microheterogeneity， analysis and structural characterization of glycans are the bottleneck of glycobiology research. Mass spectrometry， which has advantages in the ability to minimize sample consumption， obtain diverse structural information， and analyse mixtures， is an ideal device for qualitation and quantitation of glycans. The two biological mass spectrometry technologies， electrospray ionization mass spectrometry (ESI-MS) and matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS)， have been widely used in the analysis of glycan molecular mass fingerprint， sequence， linkage， and relative quantitation. This article summarizes the recent progress in the methodology investigation of glycan analysis using mass spectrometry as a fundamental analysing instrument.
