Example of a capillary LC-FTICR multiplexed-MS/MS analysis of Cys-PEO labeled polypeptides isolated from mouse astrocytes giving the identified peptide sequences. (A) Reconstructed capillary LC-FTICR-MS chromatogram. (B) The ESI mass spectrum for the indicated peak. (C) Data-dependent multiplexed-MS/MS spectrum for the four most abundant species in the preceding MS spectrum (2) obtained after SWIFT isolation and sustained off-resonance irradiation - collisionally induced dissociation (SORI-CID).
