Identification of the peptide containing Tyr613, AAPGYHMAK, by capillary HPLCFT-ICR-CID analysis. A – A selected mass chromatogram for m/z 945.5; B – mass spectrum integrated over the time window 2.5–3.5 min.; and C – tandem MS spectrum for the singly charged ion of m/z 945.5. The positions for this peptide ion in the mass chromatogram (A) and in the spectrum (B) are indicated by arrows.
