Compounds, compositions, methods for sequencing proteins and peptides, and methods for identifying proteins and peptides in a mixture, are disclosed. Compounds of formula A-B—C wherein A is a nucleophilic reactive group, B is a detectable moiety capable of being isotopically labeled, and C is a charge replacement group, are used to label the peptides at the N-terminus or the C-terminus. The tagged peptides can then be analyzed by mass spectroscopy.
本发明揭示了用于测序蛋白质和肽的化合物、组合物和方法,以及用于在混合物中识别蛋白质和肽的方法。公式A-B-C的化合物中,A是亲核反应基团,B是可被同位素标记的可检测基团,C是电荷替换基团,用于标记肽的N-末端或C-末端。然后可以通过质谱分析来分析标记的肽。
