D. Fabris et al., COLLISION ENERGY EFFECTS ON THE COLLISION-INDUCED DISSOCIATION OF MULTIPLY-CHARGED MELITTIN, Rapid communications in mass spectrometry, 8(9), 1994, pp. 791-795
The fragmentation of the melittin 4 + ion has been studied over a rang
e of collision energies from 28 eV to 12 keV in a four-sector mass spe
ctrometer. Patterns of fragmentation and energy conversion were found
to be analogous to those observed for singly charged peptides. High nu
mbers of collisions were not required for activation at low energies.
