    • Provided is a method for characterising an analyte by matrix assisted laser desorption ionisation (MALDI) mass spectrometry, which method comprises: (a) labelling the analyte with a light-absorbing label that absorbs light at a pre-determined frequency, to form a labelled analyte; (b) embedding the labelled analyte in a matrix formed from at least one compound that absorbs light, to form an embedded labelled analyte; (c) desorbing the embedded labelled analyte by exposing it to light having the pre-determined frequency, to form a desorbed analyte; and (d) detecting the desorbed analyte by mass spectrometry to characterise the analyte; wherein the light absorbing label comprises a fluorophore moiety, and wherein prior to detecting by mass spectrometry, the analyte is selected for detection on the basis of its fluorophore moiety.
    • 提供了一种通过基质辅助激光解吸电离(MALDI)质谱鉴定分析物的方法,该方法包括:(a)用预吸收光的光吸收标记物以预定的频率标记分析物,形成标记的 分析物; (b)将标记的分析物包埋在由吸收光的至少一种化合物形成的基质中,以形成嵌入的标记分析物; (c)通过将嵌入的标记分析物暴露于具有预定频率的光来解吸,形成解吸附的分析物; 和(d)通过质谱检测解吸附的分析物来表征分析物; 其中所述光吸收标签包含荧光团部分,并且其中在通过质谱法检测之前,根据其荧光团部分选择所述分析物进行检测。

    • Provided is a set of two or more mass labels, each label in the set comprising a mass marker moiety attached via a cleavable linker having at least one amide bond to a mass normalization moiety, wherein the aggregate mass of each label in the set may be the same or different and the mass of the mass marker moiety of each label in the set may be the same or different, and wherein in any group of labels within the set having a mass marker moiety of a common mass each label has an aggregate mass different from all other labels in that group, and wherein in any group of labels within the set having a common aggregate mass each label has a mass marker moiety having a mass different from that of all other mass marker moieties in that group, such that all of the mass labels in the set are distinguishable from each other by mass spectrometry, and wherein the mass marker moiety comprises an amino acid and the mass normalization moiety comprises an amino acid.
    • 提供了一组两个或更多个质量标签,该组中的每个标签包含通过具有至少一个酰胺键与质量标准化部分连接的质量标记部分,其中该组中每个标签的总质量可以是 相同或不同,组中每个标记物的质量标记物部分的质量可以相同或不同,并且其中在具有共同质量的质量标记物部分的组中的任何标签组中,每个标签具有总体质量 不同于该组中的所有其它标记,并且其中在组中具有共同聚集体的任何标签组中,每个标记具有与该组中所有其他质量标记部分的质量不同的质量标记部分,使得全部 组中的质量标记物通过质谱法彼此区分,并且其中质量标记物部分包含氨基酸,质量标准化部分包含氨基酸。
