There is provided a method of detecting in a sample the presence of an anti-M and/or anti-A and/or anti-C/Y anti-body, the method comprising contacting the sample with a diagnostic conjugate provided according to the invention, comprising an oligosaccharide which comprises at least two units of 4,6-dideoxy-4-acylamido-α-pyranose and comprising at least one -(1-3)-link between adjacent 4,6-dideoxy-4-acylamido-α-pyranose units, in which the carbon at position 5 in the pyranose is linked to an R group, where R is independently selected from —CH
2
OH, —H or an alkyl group having at least one C atom, the oligosaccharide being covalently linked to a non-saccharide molecule or to a surface.
本发明提供了一种检测样品中抗-M和/或抗-A和/或抗C/Y抗体存在的方法,该方法包括将样品与根据本发明提供的诊断共轭物接触,所述诊断共轭物包括寡糖,其包含至少两个4,6-二脱氧-4-酰胺基-α-吡喃糖单元,并且包含至少一个相邻的4,6-二脱氧-4-酰胺基-α-吡喃糖单元之间的-(1-3)-键,其中在吡喃糖的5号碳与R基连接,其中R独立选择自-CH2OH,-H或至少具有一个C原子的烷基基团,所述寡糖与非糖分子或表面共价连接。
