    • A method for the structural analysis of a saccharide is disclosed, comprising: a) providing on a surface a plurality of essentially sequence- and/or site-specific binding agents; b) contacting said surface with a saccharide to be analyzed, or with a mixture comprising a plurality of fragments of said saccharide; c) washing or otherwise removing unbound saccharide or saccharide fragments; d) adding to the surface obtained in step c) an essentially sequence- and/or site-specific marker, or a mixture of essentially sequence- and/or site-specific markers; e) acquiring one or more images of the markers that are bound to said surface; and f) deriving information related to the identity of the saccharide being analyzed from said image. The invention further provides a solid support comprising in a pre-defined order a plurality of visual or otherwise detectable markers representative of a saccharide or saccharide sequence or fragment, as well as methods and software for choosing a set of essentially sequence-specific markers for use in the method of the invention, methods for obtaining structure-related data of saccharides, and methods and apparatus for analyzing the structure of a saccharide by sequential digestion using a glycosidase or an equivalent thereof.
    • 公开了一种用于糖的结构分析的方法,包括:a)在表面上提供多个基本上序列和/或位点特异性结合剂; b)使所述表面与待分析的糖接触,或与包含所述糖的多个片段的混合物接触; c)洗涤或以其他方式去除未结合的糖或糖片段; d)向步骤c)中获得的表面添加基本上序列和/或位点特异性标记或基本上序列和/或位点特异性标记的混合物; e)获取结合到所述表面的标记的一个或多个图像; 以及f)从所述图像导出与正在分析的糖的身份有关的信息。 本发明进一步提供一种固体支持物,其以预定义的顺序包含多个视觉或其他可检测的代表糖或糖序列或片段的标记物,以及用于选择一组基本上序列特异性标记物用于使用的方法和软件 在本发明的方法中,获得糖的结构相关数据的方法,以及通过使用糖苷酶或其等同物通过连续消化来分析糖的结构的方法和装置。
