Provided are a method for easily detecting phosphorylated peptides, namely, proteins, in samples derived from living organisms or the like, a method for selectively adsorbing the phosphorylated peptides, and compounds that are highly coordinated to the phosphorylated peptides and usable in the methods. The complex compound is represented by the formula:
1
wherein X is a linker moiety, and Y is a labeling group. The compound (I) is highly coordinated to a phosphorylated peptide, and has a labeling group. Accordingly, with use of the compound (I), the phosphorylated peptide can be easily identified.
提供了一种易于检测活体生物等样本中的磷酸化肽(即蛋白质)的方法,一种选择性吸附磷酸化肽的方法,以及可用于这些方法的高度配合到磷酸化肽的化合物。该复合物化合物由式1表示:其中X是连接基团,Y是标记基团。化合物(I)与磷酸化肽高度配合,并具有标记基团。因此,使用化合物(I),可以轻松识别磷酸化肽。
