水素付着解離タンデム質量分析法による異性化ペプチドの分析
In this study, we focused on the reaction of the peptide ions containing isoaspartic acid residue (isoAsp) and hydrogen atoms in an ion trap mass spectrometer. [zn + C2H5ON]+ was observed as a specific signal for the isoAsp. The hydrogen attachment dissociation is useful for the quantitative analysis of peptide containing isoAsp.
