Analysis of multiply charged monomer and dimer ions of the amyloid β(1–28) peptide using electrospray ionization mass spectrometry and collision-induced dissociation

Tandem mass spectrometry (MS) fragmentation patterns of the Aβ1–28 monomer indicated that the entire 1–28 sequence dissociated during collision-induced dissociation (CID) process of the M 2+ , M 3+ , and M 4+ ions. Meanwhile, MS/MS analysis of the dimer showed that D 5+ dissociat...
