Method for labeling phosphorylated peptides, method for selectively adsorbing phosphorylated peptides, complex compounds used in the methods, process for producing the complex compounds, and raw material compounds for the complex compounds

摘要

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:
