[引用] Mass spectrometry of permethylated peptide derivatives; extension of the technique to peptides containing arginine or methionine

DW Thomas, BC Das, SD Gero, E Lederer - Biochemical and biophysical …, 1968 - Elsevier

For the sequence determination of oligopeptides by mass spectrometry, N-permethylated
derivatives have been shown to offer two major advantages: a) volatility is increased by
permethylation, thus permitting larger oligopeptide derivatives to be vaporized in the mass
