After photo-crosslinking and proteolysis of a photoaffinity labeled ligand to its receptor, the ester group incorporated in the ligand is cleaved by an amine with specific functionality, which displaces the bulk of the ligand from the peptide fragments, and facilitates subsequent tandem mass spectrometric sequencing.
在光交联和光亲和标记配体与其受体的蛋白水解后,配体中包含的酯基通过具有特定功能的胺被切割,进而将配体的大部分从肽片段中置换出来,从而促进后续的串联质谱序列分析。
