The present invention provides a set of novel isobaric chemical tags, also referred herein as SUGAR (Isobaric Multiplex Reagents for Carbonyl Containing Compound). These labeling tags are compact and easy to synthesize at high yield and purity in just a few steps using commercially available starting materials. The tagging reagents of the present invention comprise: a) a reporter group, having at least one atom that is optionally isotopically labeled; b) a balancing group, also having at least one atom that is optionally isotopically labeled, and c) an aldehyde, ketone, or carboxylic acid reactive group. The multiplex SUGAR tags are able to react with an aldehyde, ketone, or carboxylic acid group of the molecule to be tagged, which offers the capability for labeling and quantitation of glycans, proteins/peptides, and fatty acids.
本发明提供了一组新型等比化学标记,也称为SUGAR(含羰基的等比多重试剂)。这些标记标签紧凑,易于合成,使用商业可获得的起始材料,在几个步骤中高产量和纯度。本发明的标记试剂包括:a)报告者组,具有至少一个可选择同位素标记的原子;b)平衡组,也具有至少一个可选择同位素标记的原子;c)醛,酮或羧酸反应基团。多重SUGAR标记能够与待标记分子的醛,酮或羧酸基团发生反应,从而提供了对糖类,蛋白质/肽和脂肪酸进行标记和定量的能力。
