The present invention relates to a set of two or more mass labels, wherein each mass label comprises the formula:
X-L-M-Re
wherein X is a reporter moiety having an exact mass, L is a bond cleavable by collision in a mass spectrometer, M is a mass modifier, and Re is a) a reactive functionality for attaching the mass label to an analyte or b) the analyte, wherein each mass label in the set has an integer mass, wherein each mass label in the set has the same integer mass, and wherein the set comprises two or more subsets of mass labels, each subset comprising one, two or more mass labels, and wherein, when the subset comprises two or more mass labels, the exact mass of the reporter moiety X of each mass label in the subset is different from the exact mass of the reporter moiety X of the mass labels in the same subset and in all other subsets, and wherein each mass label is distinguishable by mass spectrometry.
本发明涉及一组两个或更多的质量标记,其中每个质量标记包括以下公式:X-L-M-Re其中,X是具有精确质量的报告者基团,L是可在质谱仪中碰撞裂解的键,M是质量修饰剂,Re是a) 用于将质量标记附着到分析物的反应性官能团或b) 分析物,其中集合中的每个质量标记具有整数质量,集合中的每个质量标记具有相同的整数质量,并且集合包括两个或更多个质量标记子集,每个子集包括一个、两个或更多个质量标记,当子集包括两个或更多个质量标记时,每个质量标记中的报告者基团X的精确质量不同于同一子集和所有其他子集中质量标记的报告者基团X的精确质量,每个质量标记都可以通过质谱分析进行区分。
