Distinction of Leu and Ile Using a Ruthenium(II) Complex by MALDI-LIFT-TOF/TOF-MS Analysis

The novel N-terminal labeling method using a ruthenium(II) complex derivative characteristically indicated a n and d n (N-terminal) fragment ions in high sensitivity by MS/MS analysis (MALDI-LIFT or ESI-CID). Although these fragment ions depended on a fragmentation process by MS/MS analytical method...
