The present invention provides a method for labelling one or more analytes in a sample, the method comprising: a) contacting the sample with one or more bifunctional linker reagents having the general formula Re1-L1-Re2, wherein Re1 is a first reactive group, L1 is a linker moiety and Re2 is a second reactive group, wherein Re1 reacts with an analyte to form a modified analyte; and b) contacting the sample with one or more mass labels, wherein Re2 of the bifunctional linker attached to the analyte reacts with a mass label to form a labelled analyte, wherein each mass label is relatable to an analyte by mass spectrometry.
本发明提供了一种标记样品中一种或多种分析物的方法,该方法包括a) 将样品与一种或多种具有通式 Re1-L1-Re2 的双功能连接体试剂接触,其中 Re1 是第一反应基团,L1 是连接体分子,Re2 是第二反应基团,其中 Re1 与分析物反应形成修饰的分析物;b) 将样品与一个或多个质量标签接触,其中附着在分析物上的双功能连接体的 Re2 与质量标签反应,形成标记的分析物,其中每个质量标签可通过质谱法与分析物相关。
