    • The present invention provides a method for immobilizing a polysaccharide (PS) to a solid surface, said polysaccharide having a keto-carboxy group (—C(═O)—COOH) or a ketal or hemiketal group corresponding thereto, e.g. derived from KDO (2-keto-3-deoxy-D-manno-octonic acid)), the method comprising the steps of: (a) forming a covalent bond between the carboxy group of the polysaccharide and a reporter molecule (RM), thereby forming a polysaccharide-reporter molecule conjugate (PS-RM), said reporter molecule comprising a recognition/substrate site (e.g. biotin or an anthraquinone); and (b) immobilizing the polysaccharide-report molecule conjugate by forming a specific bond (e.g. by photocoupling or formation of an affinity pair) between the recognition/substrate site of said reporter molecule and a reception/reagent site of the solid surface. The present invention also provides a solid surface thus obtainable and the use of such solid surfaces for diagnostic purposes, e.g. for the detection of bacterial infections from Gram-negative bacteria that are human or veterinary pathogens, e.g. enterobacteria, respiratory bacteria, urogenitial bacteria, and neuropathogenic bacteria such as Salmonella sp., Actinobacillus sp.
    • 本发明提供一种将多糖(PS)固定在固体表面上的方法,所述多糖具有酮羧基(-C(= O)-COOH)或对应于其的缩酮或半缩酮基,例如。 衍生自KDO(2-酮-3-脱氧-D-壬烯 - 辛辛酸)),该方法包括以下步骤:(a)在多糖的羧基与报告分子(RM)之间形成共价键, 从而形成多糖 - 报告分子缀合物(PS-RM),所述报告分子包含识别/底物位点(例如生物素或蒽醌); 和(b)通过在所述报告分子的识别/底物部位和固体表面的接收/试剂部位之间形成特定键(例如通过光耦合或形成亲和力对)来固定多糖报告分子缀合物。 本发明还提供了如此获得的固体表面和用于诊断目的的这种固体表面的用途,例如, 用于检测来自作为人或兽医病原体的革兰氏阴性细菌的细菌感染。 肠细菌,呼吸细菌,泌尿生殖细菌和神经病原菌如沙门氏菌属,放线杆菌属
