Novel method and reagents for generating reversibly tagged saccharides, aldehydes, carboxyl acids, or orthoacetates useful in analytical and diagnostic applications are disclosed. Saccharides are coupled at the reducing end to tagging moieties comprising a reagent selected from a ortho-diaminobenzoic(DAB)-peptide, an aldo-imidazole or N-methylated aldo-imidazole, or an ortho-phenyldiamine (OPD) or substituted OPD. The tagged saccharide further comprising detectable or functional groups coupled to the tagging moiety are provided. Kits and reagents for chromatography and mass spectrometry are disclosed.
揭示了一种用于生成可逆标记的糖类、醛类、羧酸或正乙酸酯的新方法和试剂,这些糖类、醛类、羧酸或正乙酸酯在分析和诊断应用中很有用。将糖类在还原端与标记基团偶联,所述标记基团包括从邻二氨基苯甲酸(DAB)-肽、醛基咪唑或N-甲基化的醛基咪唑,或邻苯二胺(OPD)或取代的OPD中选择的试剂。进一步提供了与标记基团偶联的可检测或功能性基团的标记糖类。还揭示了用于色谱和质谱的试剂盒和试剂。
