Free Radical Initiated Peptide Sequencing Using MALDI-TOF/TOF Mass Spectrometry

摘要: In this study, matrix-assisted laser desorption/ionization (MALDI) was applied to the TEMPO-assisted FRIPS for first time. We found that 3-HPA is optimal matrix analysis of p-TEMPO-Bz-Sc-peptides, which gives minimal precursor fragmentations. MALDI-TOF/TOF experiments on p-TEMPO-Bz-S...
